ANSYS default module changes

Monday, February 2, 2015 - 4:15pm

We have updated the default module of ANSYS on both Oakley and Glenn. The default module of ANSYS is ANSYS 14.5.7 on Oakley and ANSYS 14.5 on Glenn. For example, if you use module load ansys on Oakley, ANSYS 14.5.7 (instead of ANSYS 13.0) is loaded. We however keep the older versions of ANSYS installed on our cluster.
