7.4.8.1. Matching the Nodes
The Mechanical APDL input is:
rstmac, tsolid,1,all, tbeam,1,all,,,, 2
The output is:
******************** MATCHED NODES ********************
Node in Node in Distance
tsolid.rst tbeam.rst
33 1 0.0000E+00
521 2 0.0000E+00
526 4 0.0000E+00
531 6 0.2220E-15
536 8 0.4441E-15
541 10 0.8882E-15
546 12 0.1776E-14
551 14 0.2665E-14
556 16 0.3553E-14
5000 50 0.0000E+00
If there is no pair of nodes within the tolerance specified (TolerN), the node matching is failing. The default
tolerance is 1%. Only the matched nodes will contribute to the MAC calculations.
If you want to match a set of selected nodes only, you may do one of the following:
• Write only the solutions at the desired nodes into the .RST file using the OUTRES command (at the
solver level).
• Specify a component name (Cname) on the RSTMAC command. This component must be based on
the desired nodes.
7.4.8.2. Mapping the Nodes
First, the database corresponding to tsolid must be resumed.
Note
When comparing the nodal solutions of cyclic symmetric structures, the database must be saved
after the solution is finished.
The Mechanical APDL input is:
rstmac, tsolid,1,all, tbeam,1,all, -1,,, 2
The output is:
