ANSA v13.1.2 for CFD

The official software release is comprised by the latest ansa_v13.1.2 files that reside in the server at the time of this announcement. These replace any pre-releases and files downloaded prior to this date (i.e. February 11th, 2011).

Starting ANSA for CFD:

To get optimum functionality for CFD pre-processsing start ANSA in the recommended CFD-tuned mode either by:
[installation_path]/ansa_v13.1.2/ansa64.sh
which opens the ANSA Launcher window where you can select the CFD mode,
or directly (if the launcher does not appear due to installation issues) by using the extra argument - gui CFD:
[installation_path]/ansa_v13.1.2/ansa64.sh -gui CFD
