Constructor & Destructor Documentation

◆ MapTriangle3d() [1/2]

concepts::MapTriangle3d::MapTriangle3d	(	const char *	map,
		Real	scX,
		Real	scY
	)

Constructor. The values of scX and scY are only for the map, they are not needed by the user for mapping a point from the reference element onto the Real element.

Parameters

map	The element map for this triangle as a string, x and y are the allowed variables, the first and the second component are separated by a comma.
scX	The range of x is [0, scX].
scY	The range of y is [0, scY].

◆ MapTriangle3d() [2/2]

concepts::MapTriangle3d::MapTriangle3d	(	Real3d	vtx0,
		Real3d	vtx1,
		Real3d	vtx2
	)

Constructor. Takes the three physical corners of the triangle and computes the element map: $F_K : S \rightarrow K$ with $\vec x = F_K(\xi) = B \cdot \vec \xi + \vec b$ , where $\vec b = \mbox{vtx0}$ and $B = [ (\mbox{vtx1} - \vec b) (\mbox{vtx2} - \mbox{vtx1}) ]$ .
