GEOMECHANICS_SUBSURFACE_COUPLING

Information regarding the coupling between flow and geomechanics is provided here.

Required Cards:

GEOMECHANICS_SUBSURFACE_COUPLING <string>
Provide the type of coupling under <string>. Options include: ONE_WAY_COUPLED and TWO_WAY_COUPLED. The ONE_WAY_COUPLED option will only update pore pressure in the geomechanics side of things and use it for calculations of stresses and strains. TWO_WAY_COUPLED option will also update the material properties (porosity, permeability) on the flow side of things based on information from geomechanics.
MAPPING_FILE <filename>
Provide the filename of the flow to geomechanics mapping. The first column should be flow cell ids and the second column should be geomechanics vertices.

Examples

GEOMECHANICS_SUBSURFACE_COUPLING ONE_WAY_COUPLED
  MAPPING_FILE flow_geomech_mapping.dat
