Hi, Things can also be unstable because the starting configuration is too wrong for the model at normal step sizes, even when the model is valid, because the forces produce movements that are too large for the time step. You should also consider being super gentle as you start equilibration, e.g.

Dear Gromacs Users, I have been trying to simulate a docked complex of cellobiohydrolase with cellotriose for the past 1 week. I have derived the parameters of ellotriose from ATB server and with these parameters I am getting LINCS warning at the nvt equilibration step, which I assume is due to th
