Tips & Tricks

Heat Sources in Sysweld

From finite element point of view, a heat source is modelled in SYSWELD by a volume density of energy named Qr (W/mm3) applied to elements, which move along the welding trajectory.

Using Region sources in CFD-VisCART

In order to control grid spacing at user-defined locations, mesh sources are a common tool in CFD-VisCART (Figure 1). Point, Line, Curve, Plane, Box and Surface sources have been available for several years. Cylinder and Sphere sources were introduced a few years back. To extend this tool set further, CFD-VisCART V2013.0 introduced Region sources.

Arbitrarily 3D shaped surfaces

This paper illustrates the modeling process to be applied by a Visual-Mesh user with the objective of creating one arbitrarily 3D shaped surface starting from scratch.

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.
