static

Parameters

mesh	destination mesh
filename	complete filename
my_material	material to be given to the shell
node_ave_area	output the average area of the nodes
BC_nodes	material to be given to the shell
pos_transform	optional displacement of imported mesh
rot_transform	optional rotation/scaling of imported mesh
scaleFactor	import scale factor

BSTShellFromObjFile()

void chrono::fea::ChMeshFileLoader::BSTShellFromObjFile ( std::shared_ptr< ChMesh >  mesh, const char *  filename, std::shared_ptr< ChMaterialShellKirchhoff >  my_material, double  my_thickness, ChVector<>  pos_transform = VNULL, ChMatrix33<>  rot_transform = ChMatrix33<>(1)  )

static

Load a triangle mesh in Wavefront OBJ file format, and convert it into a mesh of shell elements of ChElementShellBST type.

Parameters

mesh	destination mesh
filename	.obj mesh complete filename
my_material	material to be given to the shell elements
my_thickness	thickness to be given to shell elements
pos_transform	optional displacement of imported mesh
rot_transform	optional rotation/scaling of imported mesh

FromAbaqusFile()

void chrono::fea::ChMeshFileLoader::FromAbaqusFile ( std::shared_ptr< ChMesh >  mesh, const char *  filename, std::shared_ptr< ChContinuumMaterial >  my_material, std::map< std::string, std::vector< std::shared_ptr< ChNodeFEAbase > > > &  node_sets, ChVector<>  pos_transform = VNULL, ChMatrix33<>  rot_transform = ChMatrix33<>(1), bool  discard_unused_nodes = true  )

static

Load tetrahedrons, if any, saved in a .inp file for Abaqus.

Parameters

mesh	destination mesh
filename	input file name
my_material	material for the created tetahedrons
node_sets	vect of vectors of 'marked'nodes
pos_transform	optional displacement of imported mesh
rot_transform	optional rotation/scaling of imported mesh
discard_unused_nodes	if true, Abaqus nodes that are not used in elements or sets are not imported in C::E

FromTetGenFile()

void chrono::fea::ChMeshFileLoader::FromTetGenFile ( std::shared_ptr< ChMesh >  mesh, const char *  filename_node, const char *  filename_ele, std::shared_ptr< ChContinuumMaterial >  my_material, ChVector<>  pos_transform = VNULL, ChMatrix33<>  rot_transform = ChMatrix33<>(1)  )

static

Load tetrahedrons from .node and .ele files as saved by TetGen.

The file format for .node (with point# starting from 1) is: [# of points] [dimension (only 3)] [# of attributes (only 0)] [markers (only 0)] [node #] [x] [y] [z] [node #] [x] [y] [z] etc. The file format for .ele (with tet# starting from 1) is: [# of tetrahedrons] [dimension (only 4 supported)] [# of attributes (only 0)] [tet #] [node #] [node #] [node #] [node #] [tet #] [node #] [node #] [node #] [node #] etc. If you pass a material inherited by ChContinuumElastic, nodes with 3D motion are used, and corotational elements. If you pass a material inherited by ChContinuumPoisson3D, nodes with scalar field are used (ex. thermal, electrostatics, etc)

Parameters

mesh	destination mesh
filename_node	name of the .node file
filename_ele	name of the .ele file
my_material	material for the created tetahedrons
pos_transform	optional displacement of imported mesh
rot_transform	optional rotation/scaling of imported mesh
