Welcome, @Howida_Nail

An error like this:

means that the tool completely died out and nothing could be rescued.

You could try a rerun. The public servers process many thousands of jobs each day. Some can fail by chance.

Other reasons can be problematic inputs or parameters – but try the rerun first before troubleshooting the other details.

Thank you, Jennaj, for your response. I’ve attempted to rerun the simulation multiple times, but I’m consistently encountering the same error. The energy minimization step in GROMACS produces satisfactory results, but the error arises when I proceed to the subsequent simulation step. I’m trying to identify the reasons behind this issue.
