Fields

Data Type	Variable	Description
integer		Version.
integer	type	Object type: 0 for a point object, 1 for a curve object, 2 for a surface object, 3 for a solid object, and -1 for a mixed object.
Boolean		1 if void regions are labeled; 0 otherwise.
double		Relative geometry tolerance.
double		Relative resolution tolerance.
integer	nv	Number of vertices.
VertexData[nv]	vertex	Matrix of vertex data.
integer	npv	Number of parameter vertices.
ParamVertexData[npv]	pvertex	Matrix of parameter vertex data.
integer	ne	Number of edges.
EdgeData[ne]	edge	Matrix of edge data.
integer	npe	Number of parameter edges.
ParamEdgeData[npe]	pedge	Matrix of parameter edge data.
integer	nf	Number of faces.
FaceData[nf]	face	Matrix of face data.
integer	nc	Number of curves.
GeomCurve[nc]	curves	Vector of curves.

GeomSurf[ns]	surfaces	Vector of surfaces.
integer	npc	Number of parameter curves.
GeomCurve[npc]	pcurves	Vector of parameter curves.
integer	na	Number of attributes.
Attributes[na]		Attributes. The Attribute type is undocumented because it is only used internally.

In the table above, the entity types are defined as follows:

VertexData

Entity/Object	Variable	Description
double[3]		Coordinates of the vertex.
int		The domain number if the vertex is isolated. If the vertex is not isolated this value is unspecified.
double		Relative tolerance of the vertex.

ParamVertexData

Entity/Object	Variable	Description
int		Vertex index (1-based).
double[2]		Parameter values in the surface.
int		Face index (1-based).
int		Surface index (1-based).
double		Relative tolerance for the vertex.

EdgeData

Entity/Object	Variable	Description
int[2]		Start and end vertex of the edge, respectively (1-based).
double[2]		Parameter values of the start and end vertices.
int		Index of a domain if the edge is not adjacent to a face, and is unspecified otherwise.
int		Signed index of the underlying curve (1-based). The sign indicates the direction of the edge relative to the curve. Is 0 if there is no curve.
double		Relative tolerance of the edge.

ParamEdgeData

Entity/Object	Variable	Description
int		Index of the corresponding 3D edge (1-based).
int[2]		Indices of the start and end parameter vertices (1-based index in the vector of ParamVertexData).
double[2]		Parameter values of the start and end vertices.
int[2]		Indices of the left and right faces, respectively (1-based). This is 0 if there is no face.
int		Signed index of the underlying parameter curve. The sign indicates the direction of the edge relative to the curve.
int		Index of the surface (1-based).
double		Relative tolerance of the edge.

FaceData

Entity/Object	Variable	Description
int[2]		The up and down domain index of the face.
int		Surface index of the face (1-based).
double		Relative tolerance of the edge.

Description

The Geom3 type represents a geometry object in 3D represented using the COMSOL kernel that is not an assembly and is not virtual. The geometry object must not be self-intersecting.
