How to Obtain Best Results within Reasonable Time from a Heat Treatment Simulation
Heat treated parts are in most cases not clamped during heat treatment, for an FEM analysis, at least a static determined clamping is needed that does not allow any rigid body motion.

Stamping/HT Chaining of 3D Ring - Restart tool in Visual Heat Treatment
This article is to show effects of heat treatment on stresses when industrial mechanical parts are stamped (or welded) by 3 typical heat treatment steps: Heating, Quenching and Tempering. Tempering is generally considered effective in relieving stresses induced by...

CFD-FASTRAN/CFD-ACE+ coupling for thermal environment simulations
In certain applications, different regions of the computational domain experiences flow conditions that are so different that it is very difficult for a single solver to produce accurate results at the extremes. In many situations, such problems can be separated and...

Motion Model Dependencies in CFD-FASTRAN
Moving-body models available in CFD-FASTRAN are highly suited to simulate complex prescribed and six-degree-of-freedom (6DOF) motions of rigid bodies. In many engineering problems, this translates to multiple bodies moving relative to one another.
