Tips & Tricks

Particle Tracing in CFD-VIEW

A Particle Trace or Streamline is the trajectory of a particle moving in a fluid. Being able to visualize/analyze this trajectory can be very helpful in understanding flow patterns and flow distribution.

Making Plots Along Constant Radius Curves

How do I plot a variable along the circumference of a circle or circular arc? The above query has been made several times by CFD-ACE+ users. In case of cylindrical geometry, it’s very useful to have a plot of the desired variable along a circle of certain radius.

Creating Strip Charts in CFD-VIEW

The Strip Chart feature in CFD-VIEW is a very useful tool for analyzing time dependent quantities from transient simulations. The feature can be found in the second row of the Operator Palette as shown. This note provides you with an overview of how to use and implement the Strip Chart feature.

Understanding cell-splitting in CFD-VisCART and its effect on cell count

A grid created in CFD-VisCART will have a high percentage of Cartesian cells (100% for Stair-Step Mesh; as high as 90-95% for Projected Mesh). Since these form the bulk of the grid, it helps to make sure that these cells are built in an efficient manner.

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.

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.
