With the new release of Fluent 5.0, it's now possible to study Free Surface Flow (see the task FSFF report) and Large Eddy Simulation (see the LESF report). Another feature is that we can use hybrid meshes.

The compatibility with the last version is kept. For example, we took a file .cas which was used to study the Rayleigh Benard convection with the version 4.0, and it worked on the new version of Fluent.

The difference comes from the new coding of User Defined Functions. The C code is completly different (see Boundary and Initial Conditions)
