class bem::rwg::ObsStrategic< ObsTriangleQuadratureType, SrcTriangleQuadratureType, LineQuadratureType >

Strategic integration over the observation triangle for RWG-based BEM operators. The method of integrationis chosen automatically and strategically based on mesh parameters, materials, and frequency.

Template Parameters

ObsTriangleQuadratureType	- Type of the observation triangle quadrature object, which must derive from `TriangleQuadratureBase<2>`.
SrcTriangleQuadratureType	- Type of the source triangle quadrature object, which must derive from `TriangleQuadratureBase<2>`.
LineQuadratureType	- Type of the line quadrature object, which must derive from `LineQuadratureBase<1>`.
