When 'abaqus cae -noGUI file.py'  is executed on an HPC remote machine, abaqus exits with an error. The following error is displayed on a log file, which seems to relate to an environment file reading problem. I have checked that  the 'abaqus_v6.env' shown in the file path below does exist. Does anyone have any idea what causes this and how to resolve it?
