"Improving Laser Manufacturing Processes B y Means of Multiphysics Simulations";
Talk: International Symposium for Production Research,
Vienna (invited);

- 2018-09-15.
English abstract:
In this paper we present an example of how laser manufacturing technology can benefit from the use of realistic process simulations. The general design of the multiphysical model used allows for the simulation of different kinds of laser processes such as welding, cutting or more recently even ultra-short pulse ablation [1]. The model is able to perform the simulation of the complete process, thus providing useful technical information such as the influence of keyhole front inclination or of surface tension on the flow of the molten material and its consequences after the solidification. In addition to the implementation of physical models, the current ongoing work presented is aimed to improve the simulation performance in massively parallel scenarios such as HPC-clusters or cloud environments, because the increasing availability of these resources shall eventually enable the application of expensive numerical calculations for production purposes.
