He developed parallel simulation software on distributed memory architectures and has successfully simulated CFD, FEA and FSI problems of sizes up to 20 million DOFs.
Abstract of the Report:
Simulation software packages have become indispensable tools in science and engineering. Today, mature commercial simulation software tools are available for standard applications in solid mechanics, fluid mechanics, heat transfer and electromagnetism. However, despite recent efforts, these software tools offer limited functionality for the simulation of complex multiphysics problems. These limitations have proven to be a prominent impediment to the optimal design of complex engineering systems, to the optimal control of manufacturing processes and to advance scientific research on complex multiphysics problems. On the other hand, the ever-increasing need for improved-quality and cost-effective products, and the advancements in multifunctional composites for applications in energy harvesting, soft robotics and energy storage, mandate sophisticated simulation tools equipped with multiphysics simulation capabilities.
To address the existing gaps in multiphysics simulation capabilities, my research over the last decade has been focused on developing novel computational methodologies that are efficient and robust for multiphysics problems, and their computer implementations for high-performance computing. Simulation of multiphysics problems in a computationally efficient poses numerous challenges in terms of finite element formulations and their computer implementation. In this invited talk, I present the computational methodologies I have developed for complex fluid-structure interaction problems and large-deformation and large-strain behaviour of smart multifunctional composites such as electro-active and magneto-active polymers, including the effects of viscoelasticity, elastodynamics and growth effects.
