Detailed Description

Types of domains for integration rules and reference finite elements: Geometry::POINT - a point Geometry::SEGMENT - the interval [0,1] Geometry::TRIANGLE - triangle with verteces (0,0), (1,0), (0,1) Geometry::SQUARE - the unit square (0,1)x(0,1) Geometry::TETRAHEDRON - w/ vert. (0,0,0),(1,0,0),(0,1,0),(0,0,1) Geometry::CUBE - the unit cube
