No, you can do it as long as you make everything consistent. Be wary of the force discontinuity from the dashpot if you’re using hooke/history. Attractive potentials and it don’t play nice together.

hi eric thanks…but when I am putting granular style along with the lj96/cut it’s saying wrong arguments for the granular style…whereas I have given the style arguments properly
