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.

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.

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.

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.
