      Hello, I am trying to perform a topology optimization (Static Structural in Mechanical, version 2025R1), but I get the following error:

      "Error reading ENF from D:\XXX_files\dp0\SYS\MECH\file.rst for result set 1" - I understand that ENF means Element Nodal Forces and I could obtain these through result set in load case itself.

      Previously, the optimization has worked perfectly and it still does for larger elements. Could this be because of large .rst file? Is there any known solution for this error? Thanks in advance for any feedback, I wasn't able to find anything online.
