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.

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.

Coupling between PAM-FORM and PAM-RTM: multiple part mapping
Coupling between PAM-FORM 2G and PAM-RTM is done through a .DSY file. Thus, pre-forming process is simulated with PAM-FORM 2G and resulting fiber orientations that will affect permeabilities are transferred to PAM-RTM model setup.

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.
