Tips & Tricks

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.

Splitting a Model in CFD-VisCART
CFD-VisCART is a 3D unstructured adaptive Cartesian mesh generator. It is ideally suited for external aerodynamics and automotive underhood applications involving extremely complex geometries. Models/geometries in SAT, Parasolid, STL, Nastran, 3DS, Plot3d and FAST formats can be imported into CFD-VisCART.

Grouping Objects in CFD-VisCART
When handling complex geometries in CFD-VisCART, the list of geometric surface can quickly become very large and make the management of the model rather tricky.

Gridding a Hemisphere in a Box with a Structured Butterfly Grid
Since spheres, hemispheroids, ellipsoids, and related geometries are very common in a great variety of problems, some techniques have been developed to mesh this class of geometries with structured grid systems. Just as a butterfly grid can be used to grid a circular face, here we will demonstrate how this approach is used to create a 3D butterfly grid for meshing a hemisphere.

DTF utility: the -vd and -ud options
The DTF utility offers several options for viewing and manipulating simulation data in a DTF file. Simulation data is essentially all settings that are not Volume Conditions or Boundary Conditions. By using a couple of DTF commands, you can update the data in the DTF file without opening it in CFD-ACE-GUI. In this tip, we will demonstrate how to use the -vd and -ud options of the DTF utility.

CFD-TOPO: A Tool for Feature Scale Simulation of Semiconductor Processes
CFD-TOPO is a simulation tool that predicts how the shape of entities change due to the combined effects of chemical species transport and surface reactions at gas-solid interfaces. This application provides a wide array of tools to analyze the steps of a semiconductor process on the feature scale of a device (typically the order of micro-meter).

Automatic Report Generator in CFD-CADalyzer
The Report Generator in CFD-CADalyzer allows a user to generate and print a detailed report of the CFD simulation that has been set up and run. The user can also customize the report to make it fit his/her needs and demands.

File Based Animation with CFD-VIEW
The animation panel in CFD-VIEW can be used for file-based animations, where time dependent data files are loaded one by one to show the temporal aspects of the simulation.

Get a Better Grip on CFD-GEOM by Setting the Rotation Point
In the CFD-GEOM graphics window, your model rotates around a 'rotation point'. By default, the rotation point is located at the geometric center of your model, which may not always be convenient. You can easily change the rotation point using the rotation point icon on the toolbar.
