You can load OpenFOAM data directly into EnSight 9.2 and 10 using the OpenFOAM Reader.  You can do this at the command line, or via the GUI of EnSight.  This tutorial shows you how.


Or, you can of course continue to convert your OpenFOAM data into EnSight Case format using the translator.


Update:  OpenFOAM reader in EnSight 9.2.2. and later supports parallel OpenFOAM datasets without requiring reconstruction to a single file!
