Adaptive Mesh Refinement

Automatic adaptive meshing in HFSS is an essential and integral part of the simulation process. An appropriate mesh that supports electromagnetic calculations is essential to obtain accurate results. In HFSS, meshes representing the design and its electromagnetic characteristics are produced automatically ensuring efficient simulations in generating accurate results.

HFSS has always supported single frequency adaptive meshing. In this method, HFSS starts with an initial mesh, determines the mesh induced solution errors at a single frequency, and then refines the mesh at locations with the highest error. This process continues until the convergence criteria is satisfied and the solution converges.

The adaptive mesh refinement process is enhanced by the multi-frequency adaptive meshing feature, which generates solutions at several frequencies and combines the mesh induced solution errors across these frequencies to determine locations where further mesh refinement occurs. This iterative adaptive refinement continues until the solution converges. This ability to adapt the mesh at multiple frequencies yields more accurate solutions across a broad frequency range.
