2.3.9. COMAC Table

The COMAC table is produced when a new successful MAC calculation has taken place or when the Preview Matched Nodes option from the MAC Frequency Worksheet is generated. It is shown at the same location as the 2D MAC Table.

For the Matching Nodes algorithm option (Data Interpolation property set to No) it displays the list of nodes that have been matched between File 1 and File 2. The selected nodes in the table are highlighted in magenta (File 1 Node) and green (File 2 Node) in the Geometry pane.

 

For the Mapping Nodes algorithm option (Data Interpolation property set to Yes) it displays the list of nodes from File 2, and N/A for all the corresponding nodes of File 1. This happens because the Mapping Nodes algorithm calculates the node2-equivalent result from the contribution of all the nodes in File 1, based on their proximity. The selected nodes in the table are highlighted in green (File 2 Node) in the Geometry pane.

 

You can also use the COMAC table to compute and display COMAC results. Trigger the calculation by clicking the button above the table. To produce a successful set of COMAC results, the same number of modes must be ticked in the MAC Frequency Worksheet (by either having previously run the Mode Pairing Algorithm or by manually ticking the modes). Calculating the COMAC results supplements the table with COMAC columns.

 

Finally, the information displayed in the COMAC table can be exported to a CSV file when the Export to CSV button is pressed.
