This is a crash that occurred inside the PLUMED library, I suggest to seek help from the PLUMED community. ---

Anyone found a fix for this? I’m having the same problem. If I run it without plumed, it runs fine, so I dont think it’s the system blowing up. ---

> [@BiaFonseca](#): > > If I run it without plumed, it runs fine This confirms what @pszilard said above - it’s a PLUMED problem, not a GROMACS problem. Inquire with their help forum. ---

I’ve realized it was because I had the geometry file in the plumed .dat file as .gro, when it has to be in .pdb format. Worth checking if anyone is having a similar problem.
