Detailed Description

template<typename POSPRED>
class lf::refinement::EntityCenterPositionSelector< POSPRED >

Utility class: selection of entities according to the position of their midpoint.

Template Parameters

POSPRED

predicate depending on physical point location

Type requirements

POSPRED must have an evaluation operator that accepts an Eigen matrix/vector object whose columns are viewed as coordinate vectors. It should return a boolean value.
