Command ID (required)
sid
Particle subdomain ID
itype
Interaction type
options:
0 $\rightarrow$ no coupling (DP, SPH)
1 $\rightarrow$ blocking (SPH)
2 $\rightarrow$ porous (DP, SPH)

Description

This command is used to define the interaction between the CFD domain and overlapping discrete soil or SPH particles.

Note that all SPH particls are, by default, coupled with a blocking type interaction. Hence, this command with itype=0 can be used to turn off the coupling.
