Hi, Sorry that was so painful for you. The LINCS documentation in the manual suggests that that combination of bonds becoming constraints won't work well. Perhaps we should add a 3-edge cycle detector to grompp? If you actually want a rigid planar DMSO, then three real atoms and a virtual site

Hi everyone, I never got a reply to my message but I figured out the problem by myself. Just in case anyone else runs into a similar problem I thought I should explain what was wrong and share the solution. I was using a DMSO topology from the ATB that uses extra bonds to fix the geometry
