Display mesh nodes in Visual Viewer based on internal number ID

Today it is not possible to display internal number of node within visual viewer. The only way is to display internal number within Sysweld/systus solver, check for the corresponding user defined one and come back in visual viewer to display the user define one. Meanwhile in the .Log file only internal nodes are listed. ITERATION 0 MAX. RESIDUE 0.414E-01 NODE (INT) 14817 COMPONENT 1

Solid elements morphing by twist in Visual Mesh

In the case of 3D meshes, the term morph can be interpreted as the change of appearance of a graphical object. The morphing process is then defined as the construction of an animated sequence corresponding to the gradual transition between two different objects, so-called source (initial) and target (final) models. The objective of a morphing method is to compute a transformation ensuring a visually pleasant transition between the two, source and target shapes

Management Unconnected Mesh in Visual Weld

Meshing is still a difficult task today especially when the geometry of the structure is complex. With the help of “Connect Edges” function in Visual Weld, it is no more mandatory to have mesh nodes connected between components and weld beads. It ensures connection between non-connected mesh properties.The result quality between connected and unconnected computation variants are almost identical and the computation time is nearly the same. The thermal and the mechanical compatibility will be ensured thanks to the automatically generated specific transition elements.

How to simulate welding process with variable weld speed and Heat power ?

In real process, the user changes the velocity depending to the distance already covered or still to cover in welding process. To better reproduce the start and the end of a welding process, the velocity must be able to vary during at least these two phases as well as the heat source power. And to be more generic, this feature introduces a time dependency of the heat source velocity and its power density.

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

Restart Sysweld thermo-metallurgy and mechanical calculation in batch mode

The aim of this article consists to show sysweld/systus users how to perform a restart computation when a calculation run in batch mode is stopped in middle for some reasons or not.

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.

Friction Stir Welding modelling with an Axi-symmetric tool

Friction Stir Welding (FSW) is an innovative technology, which allows a solid junction of heterogeneous alloys, using a wear-resistant rotary tool that follows the welding seam. ESI Welding solution allows todays to predict temperature generated by FSW process. The proposed methodology is based on local approach that cannot give global distortion of the welded components. The aim of this article is to show how user can setup it own FSW process and run the computation using Visual Weld application

Welding simulation with FAST3D method in Visual Weld

A new method is described, which allows to reduce computation time significantly. It is used for transient simulations with moving heat source, mainly for long welds. Its advantage is that it does not require any additional manipulations with the model.

Interface SYSWELD / ABAQUS

The objective of this interface is to perform a restart with ABAQUS using a SYSWELD computation. The difficulty is to transfer the metallurgical effects in a data structure which is not designed for it.
