Tips & Tricks

How to fill multiple holes of different shapes and sizes on a plate?

Using Visual-Mesh, you can fill small holes of different diameters with a surface easily. This can be achieved with the Surface Trim option available in the surface menu.

How does Batch Mode execution work in Visual-Environment?

To run the scripts in Batch mode

How to filter entities in the Explorer?

You can filter entities based on Name and ID and also list the referred entities

How to create your own toolbars in Visual-Environment?

You can create your own toolbars using Tools->Customize

How to change user home location in Visual-Environment?

You can change the Home and Temporary directory path from General Preference or from the Variables

How to make an advanced selection in Visual-Environment?

Advanced Selection allows you to select entities in different ways such as column wise, sheet wise, etc. It also allows you to stop the selection at non manifold T-Sections based on feature angle.

Automatic covering of larger unwanted holes in CFD-VisCART

CFD-VisCART meshing automatically closes or covers holes in the geometry that are smaller in size than the cell size specified at the surfaces. To cover LARGER holes, the ‘Max Hole Size to Cover’ feature can be used. This feature, introduced in V2013.2, works to automatically cover larger holes in the geometry during mesh generation, and thus prevents the mesh from leaking into unwanted regions. This feature is available with all mesh types supported in CFD-VisCART.

Grouping parts during data import in CFD-VisCART

When dealing with complex industrial models such as cars and airplanes, hundreds of parts need to be managed. Each one of these parts may also be subdivided into different components. In order to easily manipulate these different parts and components in CFD-VisCART, you can make use of the grouping feature.

CFD-VisCART: Mesh Extrusion

In most CFD simulations, it is required to place inlets/outlets far enough from the region of interest in order to reduce their influence on the solution. In many applications, this can be done by extruding existing inlets/outlets BC patches away from the domain.

Preserving boundaries between patches with CFD-VisCART’s Single Domain mesher

The ‘Preserve Features’ option does very well in preserving features between geometry patches – as long as the patches are not coplanar (dihedral angle = 0) or include a very small dihedral angle between them.
