Hello,nAre you seeing this issue when you run Chemkin on any generic model? Or do you see this happen specifically only on the model you are currently running? Are you able to open other Ansys Products - Fluent perhaps?nIf this is only an issue with Chemkin, could you please completely uninstall your java application and reinstall the latest version?nAlso, which version of Ansys are you using?nThank you.nKarthikn
