Abstract

The aim of the sub-project is to extend the simulation tool for LSS-K, LSS-M and SEBM from the first two funding periods to a hierarchical simulation environment in order to develop and qualify problem- and parts-adapted simulation strategies. This requires the application of reduced physical models, compensation strategies for error reduction and efficient algorithms, e.g. adaptive multi-rate time integrators. The process simulations (for parts up to 1000 cm³) will support the process control for the reproducible production of parts with defined properties.
