Tips & Tricks

Importing an arbitrary STL surface for post-processing in CFD VIEW

When using the Arbitrary-Cut operator, you have the option to directly import an external surface in STL format into the model. This option, which was first made available in V2013.4, underwent significant performance improvements in V2014.0. This option provides the ability to plot data and process information on any arbitrarily shaped surface. The import process involves reading the STL file and computing the intersections between this surface and the model’s volume cells. Results on the imported surface are interpolated from the intersected volume cells and are independent of the surface mesh size of the STL as long as the surface is properly represented.

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.

Using a template CDL file for quick case set up in CFD-CADalyzer

If your simulations with CFD-CADalyzer typically include the same or similar type of physics, materials and boundary conditions then you can make the case setup process very efficient and quick with the use of a template file - a CDL file that includes the typical simulation settings.

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 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?

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.
