Using Arbitrary Interfaces for Sliding Meshes in CFD-ACE+

When using the Grid Deformation module in CFD-ACE+ with systems containing rotating parts, the system may require the grid to rotate 360 degrees. However, this is not possible since the grid will become highly skewed/stretched.

Changing Solver Control Parameters on the Fly via the MOD File

The MOD file can be used to change some solver control parameters while the solver is running. The idea is that some solution control and output control parameters can be modified by creating a modelname.MOD file,  without stopping and restarting the simulation.

Using Cyclic Boundaries in CFD-ACE+

There are many applications that involve rotating mechanical components that result in rotational or circumferential symmetric flows. One can model an entire 3D rotating system, but the computational resources to do so can be quite large.

Understanding the Mass Flow Summary Output

Some of the modules have the capability to produce a summary report of computed data. These summaries are usually integrations of some parameter over each valid boundary patch, as well as a summation of all of the data for the whole model.
