When suddenly pmdb-files cannot be opened anymore in Fluent Meshing on Linux with the below error message, then one reason can be a full /tmp directory. The /tmp-directory is the default location for storing temporary data by Fluent Meshing. This can be changed in the Preferences settings. /ansys_inc/v201/aisol/.workbench: line 165: 37737 Aborted “ansys_inc/v201/aisol/CommonFiles/linx64/ansys.meshing.fieldmesher.exe” “-B” “/ansys_inc/v201/commonfiles/CPython/3_7/linx64/Release/python/../Ansys/TGrid/CADReaders.py” “-a” “/tmp/options1601467043.63653736953.xml” “-a” “/tmp/options1601467043.63653736953.xml” Error: Error in CAD Import Error Object: #f Error: Error occurred during import.
