Cell Size Growth Control in CFD-VisCART

In CFD-VisCART, the Cartesian cells can split or grow by a minimum factor of 2 because of the intrinsic cartesian-cell-splitting algorithm. Due to this, in some cases, there is a chance that the mesh could grow from dense (at the wall) to coarse (away from the wall) within a short distance.

 

CFD-VisCART 'Save Image' feature

As in CFD-VIEW, CFD-VisCART has a 'Save image' feature that allows you to save snapshots of you model. If you are interested in this tip, please read on.

Distance Measuring Tool in CFD-VisCART

CFD-VisCART has a simple and easy-to-use tool for measuring the distance between two points in a geometry. This tool can be found under the Geom tab.

New Tools in CFD-VisCART v2006

CFD-VisCART is best suited for aerodynamic and automotive underhood applications involving extremely complex geometries. When generating the mesh, you might encounter negative volumes in the mesh. CFD-ACE-SOLVER is not capable of handling such meshes, and thus these deficiencies in the mesh must be removed before submitting it to the solver.

Using CFD-VisCART in Batch Mode

CFD-VisCART allows you to handle extremely complex geometries with lots of details. Often, you may have a geometry that you only modify slightly, but would like to use the mesh parameters that you used previously. In order to make this very simple, a batch mode was implemented for CFD-VisCART v2006.

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.
