The purpose of this benchmark is to test the source term type of NodalSourceTerm being applied to the hydraulic equation in the computations with the Taylor-Hood elements, e.g., the pressure interpolation using linear shape function, and the displacement interpolation using quadratic shape function.
The problem is solved on a rectangular domain 2 m $\times$ 1 m. Nodal fluid flux is applied on the left boundary nodes with a value of 0.001 kg/s via the property of NodalSourceTerm. The pore pressure on the right boundary is equal to the initial pore pressure of $10^5$ Pa. The displacement in the normal direction of all boundaries except the left one is fixed.
Fluid and solid are incompressible.
All involved parameters are listed in the following tables:
|Young’s modulus (bulk)||$2.5\cdot 10^9$||Pa|
|Poisson ratio (bulk)||$0.27$||-|
The time period of 86400 is discretised into 100 steps.
The distributions of pressure and displacement at the end time are shown in the following figure:
