pressure controlling

Dear Aidan ,

I have one more question about this system ( graphene + substrate ) .
Actually I want to know your idea about fix rigid command that I have to use for this system .
If I want to consider graphene layers and substrate as rigid bodies I should use " rigid/small " with molecule body style . am I right ?


You can use either fix rigid or fix rigid/small depending on

how many bodies you have and their size. The fix rigid

doc page explains the trade-offs.
