EDF found too early in postprocess

I have this message in a popup window after calcultaion: “EDF found too early in postprocess” and i don’t know how to change it.

Can someone help me?

Thanks

This simple mean that the results file is truncated.
e.g. because the solver has crashed, or is already calculating, or has some bug,…
Probably the solver is failing because something wrong in its input, verify your data, and have a look to this input file and the output files created by the solver.
