map

       'map' <slave-set> <master-set>  ->
               ['surf']|
               ['volu']|
               [ 'x'|'y'|'z'|'rx'|'ry'|'rz']  ->
                 'ds'<nr> 'e'<nr>

This keyword is used to map (or interpolate) values from one mesh to another. For example
map slave master surf ds1 e1
will map the values from Dataset 1 and entity 1 to the nodes of set slave. The parameter ``surf'' is used for mapping of values from surface to surface like pressure. The parameter ``volu'' for mapping from a 3D mesh to another 3D mesh of the same shape (currently not available). The parameters ``x,y,z'' are used for mapping from 2D to 2D/3D in the indicated direction. The parameters ``rx,ry,rz'' are used for rotational mapping of 2D to 2D/3D around the x,y,z-axis. The ``master''-nodes must belong to elements. Unconnected nodes are not allowed. Usually the master nodes (on which the values are known) were included from an external result file with the ``read'' command (with the parameter ``add''). For further details see ``How to map loads'' in the appendix.
