Primary research areas

Current research

Title: Computer Design and Simulation Tools

Description: Fast design turn around times will allow engineers to quickly test their ideas and find the best design candidates. This can reduce development costs considerably and help explore more ideas thus resulting in an overall better final product.

• Contact Forces: One computational heavy problem is computing contact forces. Contact forces prevent objects in the real world to move through one and each other. We work on finding high fidelity and descriptive models of contact forces and fast methods for computing the contact forces. 
• GPU Computing: Another problem we address is the exploitation of the computational power of the graphics processing units (GPUs). We enhance computer graphics methods to be accurate enough for engineering purposes and we accelerate existing CFD solvers like openFOAM with GPU based computing.
• Fluid Simulation: We also perform basic research on novel computational methods for fluid problems such as accurate simulation of surface tension phenomena and detailed surface tracking. Most of our work is based on moving meshes and/or finite element modeling of fluids.

Title: Human Body Modeling and Simulation

Description: Computer simulations of the human body are valuable tools for medical research. We build models that can be used for virtual experiments or making accurate predictions of biomechanical properties that can not be obtained elsewhere.

• Deformable Models: One computational heavy problem is computing motion of human tissue and interaction between different layers of tissue. Our work focus on handling the nonlinear materials and large deformations aswell as the contact stresses at the dynamic interfaces between tissue in motion.

Teaching
