Tips & Tricks

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.

Parallel processing
“To pull a bigger wagon, it is easier to add more horses than to grow a gigantic horse.” This paraphrased quotation nicely expresses the basic concept of parallel processing. The speed of sequential computers has been doubling every eighteen months, according to Moore’...

The manufacturing of sand cores
The manufacturing of iron, steel and non-ferrous castings is achieved using a variety of casting process designs, and most of these involve the use of sand cores which form the internal shape of the casting. A good quality casting requires a good quality core....

FLEXlm protection file system
ESI group needs to license, manage and track a variety of licensing options, platform and product dependencies. FLEXlm is one of the only software that is up to this task. A simple, shrinkwrapped license management product would not be powerful and flexible enough to...

Why it is useful to describe problems in terms of non-dimensional parameters and which ones are the main important in solidification?
A dimensionless quantity is a quantity without any physical units. Such a number is typically defi ned as a product or ratio of quantities which do have units, in such a way that all units cancel. Dimensionless quantities are widely used in the fields of physics and...
