Heat Power display in Visual Weld

The aim of this development in Visual Weld 14.5 + Sysweld 2019.0 is to display the Power Density. Currently, this functionality is only available in the old SysWeld GUI. The new functionality "Heat Power Display" is available through the "Welding Utilities" menu of Visual Weld.

Delta T Offset For Bowing Effect in Assembly Process

In case of butt joint of two plates, in reality, there is an eccentricity e between the neutral phase of bending and the centre of the tendon force caused by the weld which causes the typical horse saddle of a butt welded flat plate.. A functionality Delta T Offset  has been developed in order to overcome the limitation due to the shrinkage methodology that cannot provide correct results for a butt joint with a non-symmetrical welding. With this new development, it will be possible to apply an offset value on the thermal loading between upper and lower surfaces of shell. In consequence, the horse saddle effect of a butt welded flat plate is produced with Assembly solution.

Conversion Files .fdb in .erfh5 on Network Drive

It is not straightforward to do the conversion Files .fdb in .erfh5 on Network Drive in Visual Viewer. In order to make it work properly, it is necessary to map network drive to the local machine. In this way, the files on network could be handled like on local machine and the conversion from fdb to erf will be working properly.

Crash when launching Visual on CentOS

On Linux, at moment of launching Visual-Environmnet, crash happens after having selected Visual Weld. It is possible to try following steps to solve the problem. - Launching Visual in debug mode - Downgrade GlibC to 2.12 - Install freshly NTP

Coupling windows for postreatment visualization

When comparison between results is needed, coupling windows and synchronizing animations is a key tool.

Boundary Layer Mesh tool demonstration

Easily creating a connection between a tetramesh and an hexamesh is possible, using Boundary Layer Mesh tool.

Heat Sources in Sysweld

From finite element point of view, a heat source is modelled in SYSWELD by a volume density of energy named Qr (W/mm3) applied to elements, which move along the welding trajectory.

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

Physical Optics (PO) VS. Geometrical Optics (GO)

The purpose of this article is to compare two High Frequency formalisms, namely Physical Optics & Geometrical Optics, with a brief overview of their advantages & drawbacks.
