Detailed Description

This header provides the C interface to create a cad geometry.

Typedef Documentation

◆ t8_geometry_cad_c

typedef struct t8_geometry_cad t8_geometry_cad_c

This typedef holds virtual functions for a particular geometry.

We need it so that we can use t8_geometry_cad_c pointers in .c files without them seeing the actual C++ code (and then not compiling)

Function Documentation

◆ t8_geometry_cad_destroy()

void t8_geometry_cad_destroy ( t8_geometry_cad_c ** geom )

Destroy a cad geometry that was created with t8_geometry_cad_new.

Parameters

[in,out] geom A cad geometry. Set to NULL on output.

◆ t8_geometry_cad_new()

t8_geometry_cad_c* t8_geometry_cad_new	(	int	dim,
		const char *	fileprefix,
		const char *	name_in
	)

Create a new cad geometry with a given dimension.

The geometry is currently viable with quad/hex and triangle trees. Tets will be supported soon. The geometry uses as many vertices as the tree type has, as well as additional geometry information, which is extracted from a .brep file. The vertices are saved via the t8_cmesh_set_tree_vertices function. Since the internals of this geometry are finely tuned to the .brep file it is recommended to only use it with the t8_cmesh_readmshfile function.
