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.
