A Fluid-Structure-Interaction Simulation tool for application in rotating machinery

A tool for Fluid-Structure-Interaction simulation was developed on the basis of the in-house CFD code SPARC, the open-source CSD solver CalculiX and the specially designed coupling manager FSiM. The new development exploits the advantages of block-structured meshes related to the multigrid acceleration technique, the transfinite mesh adaption method, a block-wise mesh adaption control and an efficient volume to surface mapping.
