Fields

The class is defined by the following fields:

Entity/Object	Variable	Description
integer		Version
integer	d	Space dimension (if equal to 0 no more fields)
integer	np	Number of mesh points
integer		Lowest mesh point index
double[d][np]	p	Mesh points
integer	nt	Number of element types (fives the number of repeats of the following fields)
string		Element type
integer	nep	Number of nodes 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

Description

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.

Example

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