Adaptive remeshing and simulating a chain of manufacturing process

Sammanfattning: Simulations of manufacturing process do in general need adaptive meshing techniques. These can not only make it possible to obtain the solution more efficient but they can also be necessary to enable a solution to be obtained at all. The latter is the case for processes like forging where very large deformations occur. The need for changing mesh is further emphasized when a chain of manufacturing processes should be simulated. The aim of the present work is to evaluate and demonstrate the use of adaptive remeshing techniques in simulating a chain of several individual manufacturing processes. The evaluated adaptive meshing techniques are mesh smoothing and mesh generating. These techniques are combined with metrics for element distortions and errors and methods for data transfer.
