Space and Time Adaptive Two-Mesh hp-Finite Element Method for Transient Microwave Heating Problems

Original language description

A novel, highly efficient and accurate space and time adaptive higher-order finite element method (hp-FEM) is proposed for evolutionary microwave heating problems. Since the electric field E and temperature field T are very different in nature, they areapproximated on individual meshes that change dynamically in time, independently of each other. Although the approximations of E and T are defined on different meshes, the coupling is treated in a monolithic fashion using a complex-valued approximate temperature. Numerical experiments are presented that show the novel method is clearly superior to its natural competitors ? the space and time adaptive (single mesh) hp-finite element method and the space and time adaptive two-mesh h-finite element method.In all cases, comparisons in both the number of degrees of freedom (discrete problem size) and CPU time are presented.
