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.

Figure 1. Distance measuring Tool

To measure the distance between two points:

Click on the Show Points icon on the ToolBar: The geometry nodes appear as pink colored square dots.

Figure 2. Activate points (nodes) on the geometry
Ctrl-Select two points: The selected points turn blue and the Measure button becomes active.

Figure 3. Ctrl-Select two points
Click on the Measure button to get the distance between the two points, as well as the resolved distances in X, Y and Z directions (dx, dy, dz).

Figure 4. Measured distance between the two points
To measure the distance between another set of two points, click on the background in the graphics area (to deselect the current points) and repeat steps 2-3.

If you have any questions about this tip or would like us to discuss other topics in the future, please let us know.

Grouping of Geometry Surfaces in CFD-VisCART V2008.0

In CFD-VisCART V2008.0, a new Group/Ungroup capability has been added for geometry surfaces. Grouping is useful for collecting multiple geometries having the same meshing parameters and/or boundary conditions.

Hole Detection Feature in CFD-VisCART

CFD-VisCART can handle geometries with small gaps, cracks and overlapping parts, but what if there is a big hole or opening in one of the parts that the user is not aware of? The grid will flow through this opening and the result will be a mesh that has cells both inside and outside the model. This leaves the user with the near impossible task of finding this opening. In CFD-VisCART, a Hole Detection feature has been introduced that performs this task for the user.

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.

Visual Display of Bad Cells in CFD-VisCART

Most models have certain parts or regions where the grid density needs to be higher than other areas to accommodate for steep curvatures, sharply changing topology, etc.

Using the Delete Tool in CFD-VisCART V2007

CFD-VisCART has several tools to modify/delete model entities. Very often it is useful to erase unnecessary entities or clean up dirty geometry in order to simplify it. There are three available ways to delete entities in CFD-Viscart.
