How do I create an SEA cavity using shrinkwrap?

How to create FE acoustic cavities with complex shapes

Auto Empty Folders option in CFD-GEOM

When importing large models into CFD-GEOM, you may notice that certain entities listed in the Model Manager may have a red box around them.

Adding Baffles to an Unstructured domain in CFD-GEOM

While meshing the geometries of industrial significance like mixing tanks, reactor and heat exchangers, we may encounter baffles which have negligible thickness but significant area to impact the physics of the problem in terms of momentum and heat transfer. These surfaces may be free-standing or connected to other surfaces from the domain.

New Mesh Sources in CFD-GEOM for Triangle and Tetrahedral meshing

Corner Point Sources, Surface Interior Sources and Tet Sources have been available in CFD-GEOM for several years, allowing for refinements during certain phases of mesh generation.

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.

How to report and talk about simulation time in an objective manner

Reporting or talking about simulation time is a difficult subject. In the article a way to manage this problem in an objective manner is given.

Materials in the database - Which material properties to use with respect to the three methods to simulate the heat effects of welding

A material is described with exactly one set of material properties. In simulation engineering - depending on the applied method and the moment in time when the simulation is carried out in the product development cycle - only subsets of a full material data set might be required. In this article is outlined which subset is used for which purpose, what is available in the database, and what can be simulated.
