Hi

I get the following error when using mdrun for a protein in solution. I have checked the structure and everything looks fine to me. Could you suggested anything else I could do.

Hi Gaurav,
what is your stepsize during the simulation? what is constrained? And have you run a minimization before starting the simulation?
hear from you soon
Steffen
