Adding Baffles to an Unstructured domain in CFD-GEOM

While meshing the geometries of industrial significance like mixing tanks, reactor and heat exchangers, we may encounter baffles which have negligible thickness but significant area to impact the physics of the problem in terms of momentum and heat transfer. These surfaces may be free-standing or connected to other surfaces from the domain.

New Mesh Sources in CFD-GEOM for Triangle and Tetrahedral meshing

Corner Point Sources, Surface Interior Sources and Tet Sources have been available in CFD-GEOM for several years, allowing for refinements during certain phases of mesh generation.

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?

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.

Working with Solids in CFD-GEOM - Part 1: Boolean Operations

Given that today’s users may import several complex parts into CFD-GEOM, this tip will demonstrate how to use the Solid Boolean Union Option to combine several parts into one.
