NMAP: Map nodes from one coordinate system to another.
This option is used to map a set of nodes from one coordina te system to another.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: Model data
Level: This option is not supported in a model defined in terms of an asse mbly of part instances.

“Node definition,” Section 2.1.1 of the ABAQUS Analysis User’s Manual
Required parameters:
NSET
Set this par ameter 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=RECTANGULAR to introduce a simple shift or rotation. Point a in Figure 14.4–1
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,andc.
Set TYPE=CYLINDRICAL to map from cylindrical coo rdinates. Point a in Figure 14.4–1
defines the origin of the local cylindricalcoordinate 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,andc.
Set TYPE=DIAMOND to map from skewed Cartesian coordinates. Point a in Figure 14.4–1
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 14.4–1 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,andc defines the local
plane.
Set TYPE=TOROIDAL to map from toroid al coordinates. Point a in F igure 14.4–1 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,andc.TheR-coordinate of the toroidal system is defined
