I am attempting to run a Topology Study, however, I continue to encounter an error either when creating the mesh or running the study after creating the mesh. The error states, "an unnamed file contains an invalid path". It shows me this error directly after the mesh has been completed, or immediately when I press "run study" after creating the mesh. I attempted to fix it by going the menu bar, selecting simulation->options then selecting reset all in "System Options". There I also went to "Default Options"->Results and selected "SOLIDWORKS Document Folder" and "Under sub folder", then named the subfolder "Study Results". I continued to get the error despite my attempts. I am using Solidworks 2018. What should I do?
