The Foundation of Domain Decomposition Technologies in Ansys HFSS
There have been significant advances in HFSS over the last decade. Some of these new technologies such as general domain decomposition solver, hybrid finite element-boundary integral solver (FE-BI), hybrid integral equation region solver (IE region), and more recently 3D component array and mesh fusion solvers are all based on powerful domain decomposition method (DDM). DDM is a technique that allows HFSS to exploit high performance computing (HPC) capabilities to solve EM problems of unprecedented size and scope. The basic idea of DDM is to decompose the original problem into several non-overlapping and possibly repetitive sub-domains. The continuity of electromagnetic fields at the interfaces between adjacent sub-domains is enforced through some suitable boundary conditions. By doing so, the most efficient solver or meshing technology can be employed in each domain.
