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.

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.

Weld Fatigue analysis based on the Dang Van Criteria
Numerical modeling of fatigue behavior has become critical for welding applications. For this purpose the ‘Dang Van criterion’ has been integrated in SYSWELD for fatigue evaluation of welded structure under multi-axial loadings. The Dang Van fatigue damage criterion is used to predict crack initiation and life duration of components subjected to damaging load. This criterion is based on multi-scale approach which assumes that shakedown occurs before crack initiation.

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.

The challenge of simulating casting and heat treatment
Foundries that have implemented casting simulation to shorten development time, further wish to use simulation in order to reduce the cost of subsequent processing steps. This often requires the simulation of heat treatment.

Using the BC/VC Queries tool in CFD-GEOM
Have you ever whished that you could blank/unblank or pick/unpick only interfaces in a CFD-GEOM model? You can now with the BC/VC Queries tool. This tool allows you to pick, unpick, blank or unblank all the interfaces of the current model based on the interface type (Fluid/Fluid, Fluid/Solid, etc.).
