Simulation and Optimization

Research within the group focuses on numerical modeling in engineering, principally using finite-element techniques.

The research group simulation and optimization develops numerical models for problems in solid mechanics, fluid mechanics, acoustics, and electromagnetics. The research is performed through the application of the finite element method (FEM) on problems of industrial interest, partly through the development of FEM in order to solve more general problems, or increase the speed of solution.

Modern commercial FEM-software can handle a large set of engineering problems but requires deep knowledge to produced reliable results. For research where commercial software is used, there is often a requirement to use different software and the results of one program must be interpreted and transferred to another. This is especially true for multi-physics problems such as fluid-structure interaction, thermo-elasticity, structural vibrations, acoustics, etc.

For further developing the FEM there is also a need to develop in-house software. Within the research group, the research focus is on the development of FEM for cohesive zones such as adhesive joints, thin embedded structures such as flow in cracks or reinforcement of structures with embedded fibers, beams, membranes or shells. Furthermore, the group works on the development of FEM for biomechanical applications such as blood flow and large deformations in tissues.
