Dear all,

If we have already set the surface bonded contact between two parts, do I still need to set the solid interaction between them? I find that whether or not the solid interaction is set, the results obtained from the calculations can be different.

Thanks，
Tomas

Hi Tomas,

If you have already defined your contact pairs, it is good practice to disable the Body Interactions. 
You can check the knowledge material below for more information:
