Abstract:
1. A computer-implemented method for simulating physical properties of an electromagnetic field in a user-defined domain, the method comprising: storing a user-defined domain in a memory; decomposing, with a processor, the user-defined domain into a plurality of subdomains; modeling the electromagnetic field within the plurality of subdomains, using higher-order Robin transmission conditions at interfaces between the subdomains; and computationally simulating the physical properties of the electromagnetic field in the domain based on the model, wherein the higher-order Robin transmission conditions comprise Robin coefficients that cause the simulated electromagnetic field to converge faster than a simulation based solely on first-order Robin conditions; and wherein the Robin coefficients are selected based on, at least in part: (i) a basis order of finite elements defined over a mesh grid of at least one subdomain, and (ii) constants related to two smallest side lengths of a bounding box of the user-defined domain.
