Mesh

Current Version


Entity/Object	Variable	Description
integer		Version.
integer	d	Space dimension (if equal to 0 no more fields).
integer	np	Number of mesh vertices.
integer		Lowest mesh vertex index.
double[d][np]	p	Mesh points.
integer	nt	Number of element types (equals the number of repeats of the following fields).
string		Element type.
integer	nep	Number of vertices per element.
integer	ne	Number of elements.
integer[ne][nep]	elem	Matrix of point indices for each element.
integer	ndom	Number of geometric entity values.
integer[ndom]	dom	Vector of geometric entity labels for each element.

The geometric entity numbering for points, edges, and boundaries must start from 0 and the geometric entity numbering for domains must start from 1 when defining a mesh through a COMSOL Multiphysics mesh file.

For information about the local mesh numbering for the mesh element type in COMSOL Multiphysics, see Mesh Element Numbering Conventions.

The following displays a mesh with triangular elements on a unit square. Neither point nor edge elements are present.
