Chemical-kinetic Model for Mars Atmosphere Re-entry Applications
The shock layer flow over a blunt body entering a planetary atmosphere at a hypersonic speed will dissociate and partially ionize. A reliable prediction of the flow-field for such application requires a chemical-kinetic model. For Mars atmosphere, the five species Park'94 is considered [1]. The dissociation of CO2 is producing C, CO, CO2, O and O2.

User Defined Curve Probes in CFD-VIEW

CFD-VIEW allows the user to create curve probes from a file containing XYZ data. This feature gives the user flexibility of collecting data on any specified/desired curve in the computational domain. As an example of use, these "curved line" probes could be used to sample simulation data at the same locations that experimental data was collected.

Tracking Multiple Variables with Multiple Legends

When post-processing with CFD-VIEW, one may wish to display two different variables on two different objects. This requires the use of two legends to correspond to the different color mapping of the variables. The legend tracking feature in CFD-VIEW can be used to achieve this. If this topic is of interest to you, please read on.

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.

Changing VC Settings in CFD-ACE+ during a Simulation
In some instances, you may want to modify the settings for a material property in CFD-ACE-GUI without stopping the current CFD-ACE-SOLVER run.  To do this, you can write a user subroutine to read in the new properties while the simulation is running.
