Characteristic Basis Functions Method (CBFM)

Characteristic basis functions are special basis functions for the method of moments defined on large domains (blocks) that contain large numbers of sub-domains meshed into triangles.

The CBFM reduces the total number of unknowns by discarding a number of insignificant basis functions based on a certain threshold. This leads to a reduction in solution time and memory.

Note: Curvilinear mesh elements are not supported.
