Horse saddle distortion modelling in Visual Weld

Welding of structures involves complex interactions between thermal, metallurgical and mechanical phenomena leading to residual stresses and distortions, which play a major role during subsequent service of these structures. Controlling material characteristics, residual stress and keep distortion within tolerances via the computer can significantly enhance the performance, the quality of the product and the structure’s service life

Overview of CSM Welding Advisor in Visual Environment 18.0.2

This tip is to give an overview of new CSM welding advisor in Visual Environment 18.0.2. This new advisor comes in replacement of Visual Welding advisor and uses Assembly solver to perform transient welding simulation.

Auto Empty Folders option in CFD-GEOM

When importing large models into CFD-GEOM, you may notice that certain entities listed in the Model Manager may have a red box around them.

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.
