Using "startx" for Remote Display |
In most compute environments today, users have a personal desktop
(running the Windows operating system) and have access to a remote
cluster to perform their simulations. The remote cluster usually
consists of a few to hundreds of powerful machines that are used by
many different users.

Fit to View in CFD-VisCART |
|
In CFD-VisCART, the 'Fit to View' function was
improved in V2007. It now checks the blanking status
before setting the view. In this tip, a car model
will be used to demonstrate the Fit to View
capability.

Coloring Surfaces in CFD-VisCART for Better Model Visualization |
|
A typical model imported into CFD-VisCART may contain
a number of parts and surfaces. By default, all
surfaces come in with the default color (set under
Edit → Preferences → Colors → Geometry Colors → Surfaces). Representing these
surfaces with different colors would improve the
appearance of the model and make it easier for the
user to distinguish one surface (or part) from the
other.

Using the Patch Tab in CFD-VisCART 2007 |
|
The Patch Tab in CFD-VisCART provides a tool for
naming of patches and assigning different boundary
condition (BC) types to them. The Explorer list
allows blanking, selecting and deleting of patches.
More over, it also provides useful geometrical
information for each patch.

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.
