I'm trying to contuct an electrical analysis in Digimat FE and whenever i try to post-process my results, with any combination of tasks, I'm getting an message saying the post-processing was terminated because of errors. The error in logs is "IO error 4". I also had the same outcome then trying the mechanical analysis.
Could you please contact the support by using the Web portal (Support -> My Case -> Create a New Case) that we investigate this issue with you. It could come from an analysis that didn't finish successfully.
