New ChemApp interface A completely new interface between OpenGeoSys and ChemApp was implemented. An new input file with file extension *.cap is used to invoke ChemApp during an OpenGeoSys model run. As ChemApp is a commercial code, the actual ChemApp source code files (project folder CMP) and libraries are not included in this version. If ChemApp is available, the OpenGeoSys project can be configured with the CMAKE option OGS_FEM_CAP. The ChemApp interface is implemented in four new source code files: rf_react_cap.h and rf_react_cap.cpp host the actual interface, while CAP_IO.h and CAP_IO.cpp encapsulate the functions calling and receiving results from ChemApp. The new ChemApp-related benchmarks only test the correct functioning of the interface reading in pre-calculated results files from ChemApp. An introductory presentation can be found here. A tutorial on the use of the new ChemApp interface with detailed instructions and explanations of keywords will follow soon.

New reaction interface REI The idea of this new interface toolbox is to provide generalized routines which are frequently required in the coupling of heat transport, flow, mass transport and reaction processes. This toolbox is more or less independent from the actual reaction codes used with OGS. An introductory presentation can be found here. The REI is invoked by a new input file with file extension *.rei and is implemented in two new source code files: rf_react_int.h and rf_react_ int.cpp. The following keywords and routines are currently implemented:

·         The keyword



with options "VOLUME" or "WEIGHT" defines whether concentration units for components are given in volume (usually mol/m³ l,s (liquid or solid)) or weight based units (usually mol/kg w (water)) are used. In the former case, reaction codes coupled to OGS usually require a conversion of units to molality, i.e. mol/kg w (e.g. PHREEQC) or total mol/m³ of REV in the system (ChemApp ). The conversion factors are only required when concentrations are defined in volumetric units (requiring the option "VOLUME") and can be requested in a specific reaction interface by call to the REI-function REACTINT::CalcUnitConversionFactors (long index, double *fl, double *fs, bool molal) where the input index is the current node index, *fl and *fs return the conversion factors for liquid and solid phase species and input molal (true/false) decides whether the conversion factors for molalities or total moles are returned.

In the latter case, the conversion is straightforward:

mol = mol/m³ l * porosity * saturation

mol = mol/m³ s * (1-porosity) * saturation

In the former case, unit conversion is achieved by

mol/kgw = mol/m³ l / (molw/m³l) * mol w /kg w

mol/kgw = mol/m³ s * (1-porosity) / porosity / (mol w /m³ l ) * mol w /kg w

For the unit conversion, porosities at nodes are required. These are computed as averaged values from connected element porosities. The quantity molw/m³l represents the "concentration of water, i.e. the moles of water in 1 m³ of liquid. For dilute systems, which is the default case, this parameter can be assumed constant as the product of water density and 55.50843506, the number of moles of water per kg of water: molw/m³l = densityw * molw/kgw For non-dilute systems such as brines, this approximation may not be suited and the concentration of water must be established by a an appropriate water density model. Such a model is implemented in the new geochemcalc toolbox (GCC, see below) and is invoked by the keyword $WATER_CONCENTRATION with option VARIABLE, followed by a list of names of model components or species which are evaluated in the density model, e.g.: $WATER_CONCENTRATION









With this definition, the water concentration is quantified as a function of solute content, pressure and temperature. (Note: $WATER_CONCENTRATION with option CONSTANT represents the default case, but this definition is not mandatory.) A more detailed explanation can be found here.

·         The Keywords







can be used to define the names of components representing water, dissolved CO2 or Na+, which may differ between different geochemical databases. These names are required by some REI-routines, e.g. for the water density model.

·         The Keywords




CONSTANT 298.15 ; Kelvin ; VARIABLE

can be used to set constant pressure or temperature values throughout the model domain in the REI, which can be used as input values for the reaction routine, e.g. without the need to define a heat transport process in the simulation. Calls to the functions double REACTINT::GetPressure (long node) double REACTINT::GetTemperature (long node) will then return the respective values defined with the keywords behind the option CONSTANT in units of bar and Kelvin. Instead, the option VARIABLE (without any specified value) will return local node pressures from the flow or heat transport model (if defined).

·         The Keyword

$SOLID_SPECIES_DUMP_MOLES ; mineral conc. mol/m3_aquifer


will invoke additional domain output concentrations of components in the solid phase (i.e. minerals or sorbed somponents) in units of total mol/m³ REV for every ith time step, with i as the indicated below the keyword. Additionally, nodal porosities (possibly modified from mineral dissolution / precipitation) are written to the output file.

·         The Keyword



will invoke output of restart files for all processes and process primary variables for every ith time step, with i as the indicated below the keyword.

·         The Keyword



will suppress geochemical reaction calculatiuons at nodes where water phase saturations drop below the indicated threshhold (dry out).

·         The Keyword


will allow initial geochemical equilibration between liquid and solid phase by the reaction module to modify and update solid phase concentrations. Usually, only liquid phase concentrations are updated by default.

·         The Keyword


will invoke output of initial concentrations to regular output files after initial geochemical equilibration between liquid and solid phase by the reaction module.

·         The Keyword



will invoke reading in nodal porosities, e.g. from a restart file "filename.txt" of a revious model run with transient nodal porosities from mineral dissolution / precipitation. The nodal porosities are interpolated to elements.

·         The keywords

$PCS_RENAME_INIT H2O 4.89281E+04 one

H<+> 6.05790E-02 one

OH<-> 5.33345E-06 one




TIC 1.0 (HCO3)<-> 1.0 (CO3)<2-> 1.0 (CO2)<0>




will allow manipulation of components concentrations by simple arithmetic operations before initialization of the geochemical model (_INIT), before each time steps execution of the reaction code node loop code (_PRE), or after completion of each time steps execution of the reaction code node loop code (_POST). In the first example, the components initial concentrations indicated in the list are replaced by the product of the respective values indicated with the concenration of an immobile dummy component "one" throughout the model domain. The "concentration" of the dummy component hence can be used as a scaling factor. By this, initial conditions for very large numbers of components in a geochemical system can be can modified quickly without the need to update the *.ic component by component. The list has to end with the keyword "END". In the second example the component TIC is the total inorganic dissolved carbon and is calculated as the sum of the relevant carbon complexes (HCO3)<->, (CO3)<2-> and (CO2)<0>, i.e.

TIC = 1.0 * (HCO3)<-> + 1.0 * (CO3)<2-> + 1.0 * (CO2)<0>

There are other options available for these keywords which will be explained here soon.

·         The keywords




with options will be explained here soon.

New geochemistry routines toolbox

Some routines of the Geochemcalc-Toolbox by Dedong Li for water density and gas-phase / water phase equilibria have been included in the OGS source code (project subfolder GCC). These routines currently are accessed via the REI, e.g. for quantification of the moles of water per volume of liquid phase (see above), or gas phase liquid phase equilibration (vapor-liquid-equilibrium).

PHREEQC-interface updates

The Phreeqc interface was updated to allow more flexibility in input-output between PHREEQC and OGS:

·         The new Keyword



allows specification of a different thermodynamic database file than the default Phreeqc.dat data base file

·         The new Keyword


Dolomite(dis) # comp

-m 0

-steps 100 in 1 steps


allows specification of kinetic phases using the PHREEQC input file syntax. Rate laws can be specified in the database file or in the *.pqc input file with the new keyword




10 rate = 1.0e-8

20 Area = .001

30 rate = Area * rate * (1 - SR("Dolomite(dis)"))

40 moles = rate * time

50 save moles



·         The new Keywords


CO3-2 # comp

HCO3- # comp

a_HCO3- # comp







now allow output of other quantities than primary species concentrations from PHREEQC. For these quantities (e.g. concentrations of secondary species, activities, etc.), additional (immobile) components must be defined in OGS to store the output values, i.e. for the above example the components CO3-2, HCO3- and a_HCO3- have to be defnined. For each component in the ADDITIONAL_OUTPUT list a corresponding ADDITIONAL_PUNCH statement must be provided, which invokes output of the requested quantity from PHREEQC by means of the USER_PUNCH keyword. In the example, additional output are concentrations of CO3-2 and HCO3- complexes as well as the activity of the latter.

New Reaction models in KinReact

The kinetic reaction object in OGS has been extended for kinetic dissolution of NAPL source zones and kinetic mineral dissolution / precipitation.

·         NAPL-dissolution requires a two-phase PS_GLOBAL flow with an immobile NAPL-Phase, i.e. NAPL saturation must be below or equal to residual saturation. The new model is explained in detail in a tutorial.

·         Mineral dissolution / precipitation is simulated using a Lasaga-type rate law (Lasaga AC, Soler JM, Ganor J, Burch TE, Nagy KL (1994) Chemical weathering rate laws and global geochemical cycles. Geochim Cosmochim Acta 58:2361–2386). The model is explained in detail here and here. A more detailed instruction will follow soon.

·         Other updates to the kinetic reaction object in OGS comprise a MPI parallelization of the kinetic reaction node loop, introduction of temperature dependency models for biodegradation and NAPL-dissolution, and methods for temporal deactivation of model subdomains during periods of quasi steady state. Some introductory slides can be found here.

New Poro-Perm model for porosity changes from geochemical reactions

Mineral dissolution / precipitation will result in changes of porosity and permeability. To account for these changes we introduce a new generalized routine for porosity updates, which is independent from the geochemical code coupled to OGS. The routine is implemented in the new reaction interface REI, hence a minimal (no specific keywords required) *.rei input file is required to create an instance of the REI object:



Geochemical reactions are quantified for grid nodes. Hence, porosity changes occur at the node locations. Therefore, the REI hosts a node_porosity vector, which stores the porosity values and their updates for each node. At the beginning of the simulation, the element porosities are interpolated to the node locations during initialization of the REI object. After geochemical reactions at the end of each time step, the updated node porosities are interpolated back to the element center of mass. These transient element porosities are stored as element variables with the flow process. For this, a new porosity model is introduced in the CMediumProperties class:


13 0.05 ; 13 = porosity update from geochemical reactions, 0.05 = initial porosity of material group

With this model, CMediumProperties::Porosity(...) will return the porosity from the element value vector of the flow process.

For updating permeabilities from porosity changes, the new $PERMEABILITY_FUNCTION_POROSITY model 8 was introduced:


8 Kozeny_Carman ;

;8 Verma_Pruess ;

Currently, the Kozeny-Carman and Verma-Pruess models are implemented. Usage of this keyword will overrule the permeability model defined with $PERMEABILITY_TENSOR.

Porosity updates are quantified by calculating solid phase volume changes from the sum of solid phase component concentration changes. For this, molar weights (MW) and mineral densities (MD) of the solid phase components must be defined as component properties, e.g.:







1 ; 0 = aqueous phase, 1 = matrix, 2 = biofilm, 3= NAPL


0.10008 ; kg/mol


2710 ; kg/m3

The volume change (assuming that solid phase components are defined in units of mol/m³ of solid phase) then is given by

DV = [C(t-1)-C(t)] * MW / MD * [1-n(t-1)]

and the new porosity is given by

n(t) = n(t-1) + DV

Note, that solid phase concentrations should be defined either in units of mol/m³ solid phase or in units of mol/kg of water; in the latter case a conversion of units will be performed within the porosity update routine.

New transverse dispersion model

A new model for the transerse dispersion coefficient by Chiogna et al. (Chiogna, G., Eberhardt, C., Grathwohl, P., Cirpka, O.A., Rolle, M., 2010. Evidence of compound-dependent hydrodynamic and mechanical transverse dispersion by multitracer laboratory experiments. Environmental Science and Technology 44 (2), 668–693.) was implemented.

In the *.mmp file the new keyword


;alpha_t_model graindiameter hydraulicrad betaexpo

1 0.00025 0.00005 0.5

will replace the transverse components of the dispersivity tensor by expressions depending on the aqueous diffusion coefficient of the respective transported component, the grain diameter and the flow velocity.
