Some of the parameters accumulated by forceSubModel in CFDEM-coupling, such as implForceDEM and implForceDEMaccumulated, need to be considered in my case. One problem with this attempt, however, is that the example works when only implForceDEM is true, or when both are set to false. When both are set to true, "LIGGGHTS could not find property dragAcc to write data from calling program to.ERROR on proc 3: This is fatal (.. /cfd_datacoupling_mpi.h:202 "This error. Also, there is no command for "dragAcc" in my code, and I don't know what caused this problem.
Could anyone give me a hint?
