In a cavern excavation model I’m trying to apply multiple relaxation factors to each excavation stage to simulate delay for support installation. I have done this previously in 3DEC by storing the reaction force of gridpoints along the excavation boundary and then adding this reaction force back to the model after a new relaxation command is applied (see below post)
When trying the same approach in a FLAC model however I get the error that the gridpoint applied force is an intrinsic model value that cannot be written to. Does anyone have advice or tips on how to get around this?
