Detailed Description

Domain implementation described using planes, the simplest of which would be a box.

The domain must describe an enclosed area in which the textile lies. If not enough planes are specified the domain may be infinite, in which case bad things may happen. A plane is described by a normal and a value that represents the shortest distance from the plane to the origin (0, 0, 0). The normal should point towards the inside of the domain.

◆ ClipMeshToDomain() [1/2]

void CDomainPlanes::ClipMeshToDomain	(	CMesh &	Mesh,
		bool	bFillGaps = `true`
	)		const

virtual

Clip the surface elements to the domain.

For surface elements (TRI and QUAD elements) the elements will be either kept, discarded or trimmed depending on their location relative to the domain. For volume elements (TET, HEX) the elements will be either kept or discarded. No trimming occurs in this case to avoid poorly shaped elements. The center of the element is used to determine whether the element should be kept or discarded. For certain finite element analyses simulations can be performed without any trimming.

Parameters

Mesh	The mesh instance to be clipped, this will be modified in place
bFillGaps	If set to true the resulting holes will be filled with a triangulated mesh
