AddLayer adds one layer of elements with a specified thickness
thickness on either on top or bottom of an existing mesh
input-mesh and returns the newly generated mesh
output-mesh that has an new layer.
One might want to take care that the material groups are reduced, eg. material groups should not be [0,2,5], but [0,1,2]. The new layer will have the material group number of the highest material group +1. With the switch
--copy-material-ids the MaterialIDs of the extruded layer will be kept.
The tool requires the OGS-6 node ordering in the elements. A different node ordering may lead to unexpected results. In case one might try to change the ordering using the tool
Left: A simple cube mesh with one material group (red). Right: The updated mesh where an additional layer (blue) was added on top of the domain with a second material group.
Usage for example:
AddLayer -i quad.vtu -o quad_with_new_top_layer.vtu -t 1
The tool was used to add a “soil” layer to the hydro-geological model of the Unstrut catchment within the INFLUINS project:
