报告摘要:

  Multiphysics modeling is critical in the development of novel electronic multifunctional devices. However, the modeling is extremely challenging because it must model several different, but closely coupled, physical phenomena, such as electric and magnetic fields, thermal field, and charged particles, in a seamless manner. Due to their strong coupling, these physics must be simulated self-consistently and solved simultaneously. But in the meantime, these different physical phenomena are characterized by drastically different spatial and temporal scales, which render their simulation extremely computationally intensive. Our group has been developing novel computational approaches that are highly capable of simulating multiphysics problems with an excellent accuracy, efficiency, and flexibility. In this presentation, we present our work on the development of a numerical approach for the multiphysics modeling of electromagnetic-plasma interactions based on the discontinuous Galerkin time-domain (DGTD) method with an adaptive Cartesian mesh (ACM) or adaptive basis functions. With the favorable DGTD features, this numerical approach is highly accurate, flexible, and scalable. With ACM or adaptive basis functions, the grid size or the order of basis functions in the computational domain can be adjusted in real time to achieve a desired resolution and an excellent efficiency.
