Can we couple multiple cmat in a model in PFC

is it possible to merge soft and linear parallel model together

Hello @ShivamPandey,
I am not sure what you mean by “merge” contact models together. You can certainly have both contact models assigned to the CMAT. Additionally, these contact models can be activated between pieces following certain criteria, such as ball-ball or ball-wall contact types; or even based on group assignments.

If you are asking about a model that contains features of both the Soft-bond model and Linear Parallel Bond model, then I’d suggest you look into developing your own custom contact model following the User-Defined Contact Models page.
