Tips & Tricks

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.

How to model Cable Networks & Connectors?

This paper is aimed at describing the modeling process to be applied to the terminal connectors of a Cable Network when focusing on 3D/Multiconductor Transmission Lines (MTL) coupling

How to avoid oscillatory phenomena with short circuited terminals of Cable Networks ?

Cable Networks with short-circuited terminals may exhibit Common-Mode (CM) currents with a highly oscillatory behavior. This article illustrates one solution to eliminate such behavior by considering lossy dielectric coatings varying with the frequency.

FD Interpolating Scheme near Metallic Structures

This article illustrates the PAM-CEM/FD interpolation scheme applied to compute the tangential electric field along wires’ path running near metallic structures (and aimed at avoiding the management of field components on both sides of the surface).

3D/Multiconductor Transmission Lines (MTL) Coupling VS. Stand-Alone FDTD (Accuracy)

This article is aimed at comparing the 3D/Multiconductor Transmission Lines (MTL) coupling accuracy with the PAM-CEM/FD stand-alone use, when applied to simplified wired models. Recommendations for good agreement are also proposed.

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.
