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  ...

Model clipping feature in CFD-VisCART and CFD-GEOM
For better visualization of the geometry and mesh, a model clipping feature was introduced in CFD-VisCART and CFD-GEOM V2013.0. The following sections illustrate the usage and benefits of this feature.

Improve Productivity Using Scripts [Video Format]
As simulations become more integrated with the design process, engineers often spend time on repeated operations that do not contribute to their productivity. There is a need for tools that could capture, preserve and transfer the knowledge within the organization or...

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...

The transient method – the third out of three methods to simulate the heat effects of welding
In order to meet different requirements from first design to start of production, three different methods are available in the Virtual Welding & Assembly Suite from ESI. The third one – the transient method – is used when not only distortion but also residual...

The shrinkage method – the first out of three methods to simulate the heat effects of welding
In order to meet different requirements from first design to start of production, three different methods are available in the Virtual Welding & Assembly Suite from ESI. The first one – the shrinkage method – is used in the feasibility and planning phase. Goal is...

Boundary layer meshing with CFD-ACE+  [video format]
The accuracy of a CFD solution is strongly dependent on how well the mesh resolves geometry and flow features. This is especially true for near wall regions (boundary layer) where viscous forces are not negligible compared to inertial forces.
