Here you will find articles on how to solve specific issues related to ESI's software solutions. Missing ESI products will be added progressively. Each article has a short abstract which is accessible to everyone. As logged users you can see the full article with all attached screenshots, and you can post comments related to each article.

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 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.

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.

Improve Productivity Using Scripts [Video Format]
As simulations become more integrated with the design process, engineers often spend time on repeated operations that do not contribute to their productivity. There is a need for tools that could capture, preserve and transfer the knowledge within the organization or...

Boundary layer meshing with CFD-ACE+  [video format]
The accuracy of a CFD solution is strongly dependent on how well the mesh resolves geometry and flow features. This is especially true for near wall regions (boundary layer) where viscous forces are not negligible compared to inertial forces.

How to check what software version you are running
There is a very fast and easy way to verify what software version you are running for your ESI CFD applications. You most likely know that this information is available for the GUI by clicking on 'Help → About ...', and for solvers by looking...
