Models

Maximum number of species increased to 50

Momentum sinks for solidification with the phase change model (see the User's Guide Addendum for details)

Surface tension and wall adhesion between more than two phases in the VOF model (see the User's Guide Addendum for details)

Improved accuracy for particle tracking in the discrete phase model (see the User's Guide Addendum for details)

Real gas model on Windows NT

Parallelization of thin-plate conduction model

Boundary conditions

Two-way coupling with the GT-Power 1D gas dynamics and engine simulation code (see the User's Guide Addendum for details)

Injection definitions for the discrete phase included in the boundary condition file created with the write-bc text command

Postprocessing

Range detection based on minimum and maximum values on selected surfaces (see the User's Guide Addendum for details)

More convenient ways to list and select zones and surfaces (see the User's Guide Addendum for details)

Residuals for additional solution variables available for plotting for the segregated solver as well as the coupled solvers (see the User's Guide Addendum for details)

thanks for your answer Ugur, but that's not my point. Of course a new release will add new features, but we can't guarantee that its better (it can be worse from the predecessor). In my Application, there's report problem for FLUENT 5.5, and we never met this problem using 5.3 version, i.e. if you viewing graphic window, you must close the previous window, otherwise you'll get the segment violation error. I mean, this my application problem or Fluent problem???. As you know, graphic window error is not documented. hehe....

regards, confused
