> Hello, i'm working with a 256 phospholipid membrane and i run grompp for minimization and to generate a .tpr file, so after run grompp i run the mdrun but instantly crushed with the legend: SSteepest Descents: Tolerance Fmax: 1.0000e03. No. of steps: 50,000, nan Fmax: inf, atom: 30983. Segmentation fault (core dumped). It could be by the cluster i ' m using? These are the characteristics: 512 cores CPU, 8 GPU'S, 2 visualization notes. Or it is like a Gromacs bug? Iḿ running in Gromacs 5.0.4. Or i have an error at atom 30983? I attached my .mdp file that i used for grompp of miniization. How can i solve it?Thanks
The list does not accept attachments.
An infinite force means you have severely clashing coordinates or the topology
is fundamentally broken.
