Visual-CFD Frequently asked questions with solutions

This article collects several tips & tricks for Visual-CFD users

『Simultaneous Display & Trajectory』

Visual-Viewerでは、複数のステートを表示すると同時に指標（node）の軌跡を表示することも可能です。 これにより、指標の動きをより明確にとらえることができます。

Coupling windows for postreatment visualization

When comparison between results is needed, coupling windows and synchronizing animations is a key tool.

Boundary Layer Mesh tool demonstration

Easily creating a connection between a tetramesh and an hexamesh is possible, using Boundary Layer Mesh tool.

Heat Sources in Sysweld

From finite element point of view, a heat source is modelled in SYSWELD by a volume density of energy named Qr (W/mm3) applied to elements, which move along the welding trajectory.

CFD-VIEW Colormap Options: Static, Dynamic, and Cumulative

The Colormap Settings panel in CFD-VIEW assigns colors to data sets. Identical data values on an object are displayed with the same color if they are using the same colormap display. Three options offer the user the opportunity to select the mode for updating the colormap as the underlying data changes, for example during transient simulations. These options are: Static, Dynamic, and Cumulative

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.
