fem_create_mesh_sol_3	(<mesher_pick>,<flag>,<solid_list>,<num_val>,<g_leng>, <elem_topo>,<node_list>,<elem_list>,<a_coord_frame>, <r_coord_frame>,<num_nodes>,<num_elems>, <nodes_created>, < elems_created> )


Description:
This function creates a finite element mesh on solids and returns the FEM data for the solid. It returns an integer status of zero on successful completion.
Input:
STRING	mesher_pick [ ]	Mesher to be used: "IsoMesh" or "Tetmesh".
INTEGER	flag	Integer to specify use of preview. Used only with “Tetmesh”.
STRING	solid_list[ ]	List of solids to be meshed.
INTEGER	num_val	Number of float values.
REAL	g_leng	Global element edge length.
STRING	elem_topo[ ]	Element topology.
STRING	node_list[ ]	List of output node ids.
STRING	elem_list[ ]	List of output element ids.
STRING	a_coord_frame[ ]	Analysis coordinate frame id.
STRING	r_coord_frame[ ]	Reference coordinate frame id.
Output:
INTEGER	num_nodes	Number of nodes created.
INTEGER	num_elems	Number of elements created.
STRING	nodes_created[ ]	Ids of nodes created.
STRING	elems_created[ ]	Ids of elements created.
INTEGER	<Return Value>	0 for success, 1 for error.
Error Conditions:
None.

Example:

Please see fem_create_mesh_sol_3 (p. 746) in the MSC Acumen Toolkit - Code Example.


fem_seed_display_dir_arrows	( arrow_segment )


Description:
Display direction arrows on all visible curves.
Input:
INTEGER	arrow_segment	Graphics manager segment id for arrows.
Output:
INTEGER	<Return Value>	Integer indicating the success or failure of the routine.
Error Conditions:
2001060	List overflow in %A%. Call customer support.
4	Interrupted system call.

Example:

Please see fem_seed_display_dir_arrows (p. 756) in the MSC Acumen Toolkit - Code Example.


db_get_mesh_params	( wmesh, mshcyc, relaxm, tolmsh, dgmesh, itrngl )


Description:
Gets the definition of an edge mesh from the database.
Input:
None.
Output:
REAL	wmesh	The unique internal line wmesh identifying the mesh to be retrieved from the database.
INTEGER	mshcyc	The number of elements on the edge.
REAL	relaxm	The mesh relaxm of the edge.
REAL	tolmsh	The tolmsh of the edge.
INTEGER	dgmesh	The number of meshes on the edge.
INTEGER	itrngl	True if the edge has been itrngled.
INTEGER	<Return Value>	Integer indicating success or failure of the routine. If the routine failed, this value contains an indication of the reason.
Error Conditions:
13000002	Unrecoverable database error.
External Dependencies and Side Effects:
Accesses one record in the “line” table in the database.

Example:

Please see db_get_mesh_params (p. 721) in the MSC Acumen Toolkit - Code Example.


move_mesh	( <surface_id_2 >, <surface_id_1>, <user_tolerance >)


Description:
The function moves the finite element entities – vertex nodes, edge nodes and the face nodes with the elements from one surface to another. The size of the two surfaces should be equal and the user tolerance should be at least equal to the normal distance between the two surfaces. It returns an integer status of 0 on success and 1 on failure.
Input:
INTEGER	surface_id_2	The id of the surface to which the mesh is to be moved.
INTEGER	surface_id_1	The id of the surface from which the mesh is to be moved.
REAL	user_tolerance	The value of the user tolerance specified by the user.
Output:
INTEGER	<Return Value>	0 for success and 1 for failure.
Error Conditions:
None.

Example:

Please see move_mesh (p. 778) in the MSC Acumen Toolkit - Code Example.


move_mesh_1	( <surface_name_ 2 >, <surface_name _1>, <user_tolerance >)


Description:
The function moves the finite element entities – vertex nodes, edge nodes and the face nodes with the elements from one surface to another. The size of the two surfaces should be equal and the user tolerance should be at least equal to the normal distance between the two surfaces. It returns an integer status of 0 on success and 1 on failure.
Input:
STRING	surface_name_2[]	The name of the surface to which the mesh is to be moved.
STRING	surface_name_1[]	The name of the surface from which the mesh is to be moved.
REAL	user_tolerance	The value of the user tolerance specified by the user.
Output:
INTEGER	<Return Value>	0 for success and 1 for failure.
Error Conditions:
None.
