You have pressure scaling and LINCS convergence issues, suggesting that the starting configuration is far from equilibrium, as well as potentially other issues. Gromos FF is not appropriate for graphene, and neither is turning C-C bonds into LINCS constraints, as set by your 'all-bonds' --

Hello everyone, I am simulating the evaporation of non protein molecules on a graphene sheet. I am using gromos force field and hence the lincs constrain are set to all-bonds. I have done the energy minimization and NVT successfully without any warnings. During the NPT equilibiration I got
