The Fraunhofer-Chalmers Centre offers contract research, services, algorithms and software based on advanced mathematics for a broad range of applications. Modeling, simulation and optimization are today key technologies for industrial innovation. The in-house software platform IPS is successfully used by companies in Sweden, Europe, USA and Asia, to reduce development time, cut costs and improve quality of products and processes. The state-of-the-art research on immersed boundary methods is integrated in the fluid dynamics software IPS IBOFlow™. The highly efficient implementation gives superior performance and unique possibilities for simulation of multiphase flow, conjugated heat transfer and fluid-structure interaction.
