UF_SF - UF_SF_ugs_2d_mesh_parms

Structure :- UF_SF_ugs_2d_mesh_parms_s

This structure allows specification of 2d shell meshing parameters.

Initialization :- This structure can be initialized with the
UF_SF_ugs_2d_mesh_parms_INIT macro.

Desired element type.

Desired element size. If
zero or negative, then mesher
will choose element size
internally.

edge matching tolerance.

TRUE if 2d mesh is a shell
mesh that should be formatted
to the solver. FALSE if 2d
mesh is a seed mesh and not to
be formated out to solver.

TRUE if map mesher should be
tried on faces for quad meshes
or if free mesher should be
called regardless of face
shape.

Applies only when attempt_quad_mapping=FALSE
Values are:
0 => Allow triangles OFF.
1 => Allow triangles ON & 0 Triangle
2 => Allow triangles ON & 1 Triangle

If attempt_quad_mapping==TRUE does not
apply.

TRUE if poorly shaped quads
should be split into
triangles.
FALSE if quads should be kept
regardless of quality.

if split_poor_quads == TRUE,
this is the warp quality
threshold. Any quad with
greater warp than this will
be split.

Whether to project midnodes
or not.

If midnode_option =
UF_SF_UGS_MESHER_mixed_midnodes,
any element with a jacobian
value higher than
maximum_midnode_jacobian will
have its midnodes
straightened.

Minimum angle at corner of a
face that can support element.
corners smaller than this will
be pinched out. This angle is
measured in degrees.

This controls how much variation
in element size is
desired/permitted in the mesh on
the surface of the bodies being
meshed. Valid values go from 0
to 100. This number does not
coorespond directly to any
actual meshing parameter, but
rather is a relative scale that
the user can use to indicate
their tolerance for mesh
variation. It is used
internally in the mesher to
calculate expansion factors and
a minimum element size. 0
means that there will be
minimumal element size
variation. 100 means that there
will be maximum element size
variation.
