Welding Simulation Engineering:
Reference: SWD-WN-A

Understanding Numerical Parameters and Nonlinear Geometry
Level: Advanced
Duration: 1 day
Audience: Advanced designers; simulation engineers; engineers from product development, process design and manufacturing dealing with Welding processes, from the automotive and heavy industries.
Objectives: Understand the background of numerical parameter files used in the Welding and Macro Bead Advisor in order to design numerical parameter files for the shortest possible simulation time, whilst keeping good results quality. How to get the best possible simulation models with Finite Elements using Sysweld, the leading simulation solution for heat treatment, welding and welding assembly.
Prerequisites: Course: Welding Simulation Engineering: Getting it Right (SWD-W-B) Recommended: basic knowledge of non-linear Finite Element technology and of numerical methods.
Description: This course explains the optimized usage of iterative techniques, linear system of equation solvers and automatic time stepping parameters. Discussion of the meaning and consequences of numerical parameters, with the objective of achieving the fastest possible computation without decreased quality of results. Keys to convergence – the optimization of simulation models – are examined.
