Motion Model Dependencies in CFD-FASTRAN

Moving-body models available in CFD-FASTRAN are highly suited to simulate complex prescribed and six-degree-of-freedom (6DOF) motions of rigid bodies. In many engineering problems, this translates to multiple bodies moving relative to one another.

Improvements to Parallel Simulation Setup in CFD-FASTRAN

Setting up and launching a parallel simulation has become much simpler and easier in FASTRAN. This note discusses some of these developments. Let’s start with things that have not changed. There are still two versions of CFD-FASTRAN solvers for parallel cases. The difference between the two versions is the underlying parallel communication mechanism, the choice of which is decided by the type of mesh used.

Low Mach Preconditioning and Dual Time Stepping in CFD-FASTRAN

Density-based schemes employing time-marching procedures available in CFD-FASTRAN provide excellent stability and convergence characteristics for high-speed compressible flows (typically M >0.5).

Avoiding Chimera Errors in CFD-FASTRAN

This note discusses a common error encountered by users when trying chimera meshes in CFD-FASTRAN.  Such errors are easy to avoid and hopefully this note will assist you.

Improved Residual Plotter in CFD-FASTRAN-GUI

In V2006, the Residual Plotter in CFD-FASTRAN-GUI has been improved to plot all of the output files that CFD-FASTRAN creates. In addition to the global residual history (RSL), CFD-FASTRAN may produce output files with the extensions *.RZ, *.FORCE, *.VFORCE, *.AFS, *.DYNA, *.DYNB, *.KINA, *.KINB, depending on the problem.
