How to manage small sized Reference Boxes?
This paper is introducing the “–RB” option of the FD mesh generator allowing PAM-CEM/FD users to manage one limited part of a complete CAD model, without any hand-made cleaning stage

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.

Model clipping feature in CFD-VisCART and CFD-GEOM
For better visualization of the geometry and mesh, a model clipping feature was introduced in CFD-VisCART and CFD-GEOM V2013.0. The following sections illustrate the usage and benefits of this feature.
