GEOPHYSICS_CONDITION

Sets geophysics boundary conditions. No initial conditions are needed as the geophysics ert mode is a steady-state problem.

Required Cards:

GEOPHYSICS_CONDITION <string>

Opens the GEOPHYSICS_CONDITION block, where <string> is the assigned name of the geophysics condition so that it can be referred to in card BOUNDARY_CONDITION or INITIAL_CONDITION

TYPE <boundary_condition_type>

Specifies the type of the geophysical boundary condition. Options for TYPE are

TYPE [DIRICHLET, ZERO_GRADIENT]

  • DIRICHLET: specifies a zero Dirichlet or zero potential across the entire condition. See Eq. (2) of ERT mode governing equations for details.

  • ZERO_GRADIENT: specifies a zero Neumann or zero flux across the entire condition. See Eq. (2) of ERT mode governing equations for details.

Examples
