Abstract
In industrial practice, benefit and acceptance of mathematical process models are in particular dependent on operability, and on intelligibility of the simulation results. An increase of relevance of extensive computer simulation consists in to prepare resultant multidimensional and time-dependent data in a suitable manner so that a process engineer receives all relevant process information, as far as possible, at a glance. The aggregation of computation results to comprehensive graphs and animation appropriate to human imagination is discussed for the production process of continuous casting of metals. In this case, it is above all a question of making visible quality influencing state variables in the inaccessible interior of the product just during the solidification process. An analysis algorithm similar to X-ray screening is applied. Characteristic of the algorithm is, that it generally works regardless of the type of discretisation used for FDM or FEM analysis. Accordingly, it can cooperate with remeshing algorithms adapted to solidification progress and solid shell growth. The method described is also applicable to welding and other related processes with coupled temperature, transformation, strength and deformation implications.
