Ansys/Workbench¶

Running Ansys/Workbench interactively with GUI¶

Start a DelftBlue Desktop session from Open OnDemand. Inside the desktop, open a terminal and load Ansys:

module load 2026 visual
module load openmpi
module load ansys/2023R2
runwb2

openmpi is included for MPI-parallel solves started from within Workbench.

If runwb2 aborts with a locale error

If runwb2 crashes on start-up with locale::facet::_S_create_c_locale name not valid (a SIGABRT from its bundled mono runtime), your session has LANG / LC_* set to a locale that is not installed on DelftBlue — see Locale warnings. export LC_ALL=C.utf8 before runwb2 works around it.

After the splash screen you should see the Workbench window:

Ansys Workbench running

Harmless warnings on start-up

Workbench prints a few messages when it starts in the desktop, such as X Error: ... BadValue and warnings about indirect GLX / OpenGL. With software rendering these are expected and do not affect normal use.
