LevelThis option is not supported in a model defined in terms of an assembly of part instances. Abaqus/CAEUnsupported; meshing techniques in the
Mesh module
are usually preferable.
Required parameters
- NSET
-
Set this parameter equal to the name of the node set containing the nodes to
be mapped. The nodes that are mapped are those that belong to this set at the
time this option is encountered.
- TYPE
-
Set TYPE=ROTATION to introduce a rotation of a specified angle about a given
axis defined by two points a and b
(or by the coordinates of these points). The origin of rotation is given by a
third point c (or by the coordinates of this point).
Set TYPE=TRANSLATION to introduce a translation along a given axis defined by two
nodes a and b (or by the coordinates
of these points).
Set TYPE=SCALE to scale each axis with respect to one node
a (or by the coordinates of this point).
Set TYPE=RECTANGULAR to introduce a simple shift or rotation. Point
a in
Figure 1
defines the origin of the local rectangular coordinate system defining the map.
The local -axis
is defined by the line joining points a and
b. The local –
plane is defined by the plane passing through points a,
b, and c.
Set TYPE=CYLINDRICAL to map from cylindrical coordinates. Point
a in
Figure 1
defines the origin of the local cylindrical coordinate system defining the map.
The line going through point a and point
b defines the -axis
of the local cylindrical coordinate system. The local –
plane for
is defined by the plane passing through points a,
b, and c.
Set TYPE=DIAMOND to map from skewed Cartesian coordinates. Point
a in
Figure 1
defines the origin of the local diamond coordinate system defining the map. The
line going through point a and point
b defines the -axis
of the local coordinate system. The line going through point
a and point c defines the
-axis
of the local coordinate system. The line going through point
a and point d defines the
-axis
of the local coordinate system.
Set TYPE=SPHERICAL to map from spherical coordinates. Point
a in
Figure 1
defines the origin of the local spherical coordinate system defining the map.
The line going through point a and point
b defines the polar axis of the local spherical coordinate
system. The plane passing through point a and
perpendicular to the polar axis defines the
plane. The plane passing through points a,
b, and c defines the local
plane.
Set TYPE=TOROIDAL to map from toroidal coordinates. Point a
in
Figure 1
defines the origin of the local toroidal coordinate system defining the map.
The axis of the local toroidal system lies in the plane defined by points
a, b, and c. The
R-coordinate of the toroidal system is defined by the
distance between points a and b. The
line between points a and b defines
the
position. For every value of
the -coordinate
is defined in a plane perpendicular to the plane defined by the points
a, b, and c and
perpendicular to the axis of the toroidal system.
lies in the plane defined by the points by a,
b, and c.
Set TYPE=BLENDED to map via blended quadratics in an
Abaqus/Standard
analysis.
Optional parameters
- DEFINITION
-
Set DEFINITION =COORDINATES (default) to define the local system, the axis of rotation,
the origin of rotation, or the axis of translation by giving the coordinates of
the points a, b,
c, and d whichever appropriate for
the chosen type.
Set DEFINITION=NODES to define the local system, the axis of rotation, the origin
of rotation, or the axis of translation by giving global node numbers for
points a, b, c,
and d depending on the type. This option cannot be used
with TYPE=BLENDED.

Continue, giving up to 20 control nodes, but giving at least
the eight corner nodes. If an edge of the blended mapping is to be mapped
linearly, the corresponding mid-edge control node can be omitted from the list.
This is done by inserting a line with node number 0 only (a blank line) in
place of the definition of the control node and its mapped coordinates. The
control nodes do not have to be nodes in the finite element model—they can be
nodes used just for mesh generation.
Abaqus
eliminates any nodes that are not used in the analysis model before doing the
analysis.
