Turbulence Solution on a Volume-by-Volume basis

A new option has been added to CFD-ACE+ in version 2007.2 that will allow the user to solve turbulence on a zone by zone basis, i.e. some zones can be specified as laminar while others are specified as turbulent.  This is available for use with all turbulence models in CFD-ACE+.

Restarting a Fine Grid Case from a Coarse Grid Solution

Many users have asked for a method to obtain a solution on a coarse grid and then use it as the initial guess for a finer grid.  This option can be done using the Map utility in CFD-Toolkit.

Usage of Multiple Reference Frame (MRF) Feature in CFD-ACE+

Special approaches are needed when dealing with the modeling and analysis of various complex rotating systems having a stator and a rotor, in single or multistage, with change in the frame of reference from fixed to rotating (namely fans, pumps, compressors, turbines, propellers, impellers, diffusers, stators, vanes etc.).

Using Mixing Rules in the CFD-ACE-GUI Database Manager

Mixing rules can be used to define the properties of a system. Mixing rules state the method which the solver will use to evaluate the species/analyte properties in conjunction with the local species/analyte composition to determine the computational cell properties.
