How much computation time does it take to run a simulation?
It depends on the type of welding problems and the speed of the computer used for the simulation. With regard to the computer, the speed of the CPU has the largest influence on the computation time. A large part of the computation time is spent for simulating the dynamic mechanical reactions, such as deformation and contact area evolution. Thus, spot welding simulations normally take less time than projection welding simulations. On a computer with a 3GHz CPU, it normally takes between a few minutes to half an hour for spot welding simulations. For a complicated projection welding problem with large deformation and dynamic contact area evolution, it may take several hours to complete.
