VEORIENT, VNUM, Option, VALUE1, VALUE2
Specifies brick element orientation for volume mapped (hexahedron)
meshing.
VNUM Number identifying volume for which elements are to be oriented (no default).
Option Option for defining element orientation:
KP | — | Orientation is determined by two keypoints
on the volume. Input the keypoint numbers (KZ1 and KZ2) in fields |
LINE | — | Orientation is determined by one of the lines
defining the volume. Input the line number in field |
AREA | — | Orientation is determined by one of the areas
defining the volume. The area represents the desired element top surface.
Input the area number as |
THIN | — | Align the element z normal to the thinnest
dimension of the volume. The shortest line in the volume is used to specify
the element z direction. (If more than one shortest line exists, the lowest
numbered of those is used.) Element x and y directions are not uniquely specified
by this option. ( |
DELE | — | Delete the previously defined volume orientation
for the specified volume ( |
VALUE1, VALUE2Parameters required for the element z-axis direction specification.
The meaning of VALUE1 and VALUE2 will
depend on the chosen Option. See the description
of Option above for details.
Use VEORIENT before the VMESH command to specify the desired orientation of brick elements in a mapped mesh. VEORIENT has no effect on tetrahedron meshes, extruded meshes (VROTAT, VDRAG, VEXT, etc.), or swept meshes (VSWEEP).
Proper brick orientation is essential for certain element types such as SOLID185 Layered Solid, SOLID186 Layered Solid, and SOLSH190. In such cases, use VEORIENT or EORIENT to achieve the desired orientation. For other brick element types, you may need to specify element orientation to control orthotropic material property directions without concern for the element connectivity. For those cases, the ESYS command is the preferred method of specifying the material property directions.
For Option = LINE, AREA, and THIN, the orientation
will be internally converted to an equivalent Option =
KP specification (KP,KZ1,KZ2). Use the VLIST command to
view the element orientations (in terms of KZ1 and KZ2) associated with each
volume.
