  • FEM

    Introduction to FE modelling concept. Derivation of governing equations for 1D problems (simple approach). Formulation’s generalization for 2D, ad 3D problems (weighting methods). Simplification for special cases.

  • FSI

    This seminar provides an introduction to the Fluid-Structure Interaction (FSI) capability using CFD and FEA codes based on MpCCI technology from Fraunhofer SCAI.
    FSI covers a broad scope of problems in which fluid flow and structural deformation interact and affect each other. The interaction may be thermal, mechanical, or both and can be steady or transient. Many problems involve some form of FSI. During the seminar's lectures and workshops users will learn about:
    Developing coupling strategies, Simulating FSI problems by cosimulation, Evaluating FSI algorithms,
    Using MpCCI, commercial CAE tools like Abaqus, ANSYS Fluent and open source packages like OpenFOAM, CalculiX.
