A computational bug has been fixed beginning with version 5.5b4. This bug affected user-defined fluids, whose density and thermal-expansion coefficient were not being calculated self-consistently.
Beginning with version 5.5b5, we are working on some significant new features. If you accidentally stumble upon a feature that is not yet described in the User's guide, you are in the work-in-progress zone, where the code's behavior is not yet perfected.
