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

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

Coupling between PAM-FORM and PAM-RTM: multiple part mapping
Coupling between PAM-FORM 2G and PAM-RTM is done through a .DSY file. Thus, pre-forming process is simulated with PAM-FORM 2G and resulting fiber orientations that will affect permeabilities are transferred to PAM-RTM model setup.

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 solved using loosely coupled solvers. Each solver is chosen to provide highly accurate solutions for the prevailing flow conditions.

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.
