Horse saddle distortion modelling in Visual Weld

Welding of structures involves complex interactions between thermal, metallurgical and mechanical phenomena leading to residual stresses and distortions, which play a major role during subsequent service of these structures. Controlling material characteristics, residual stress and keep distortion within tolerances via the computer can significantly enhance the performance, the quality of the product and the structure’s service life

Overview of CSM Welding Advisor in Visual Environment 18.0.2

This tip is to give an overview of new CSM welding advisor in Visual Environment 18.0.2. This new advisor comes in replacement of Visual Welding advisor and uses Assembly solver to perform transient welding simulation.

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.
