UG_IO SimSys MNODE 3D Node Data File Type

An MNODE file contains a list of node coordinates and a symmetric metric. No connectivity between the nodes is assumed.

     Number_of_Nodes : Number of source nodes.
     Met_0		 : coefficient 0 of symmetric metric.
     Met_1		 : coefficient 1 of symmetric metric.
     Met_2		 : coefficient 2 of symmetric metric.
     Met_3		 : coefficient 3 of symmetric metric.
     Met_4		 : coefficient 4 of symmetric metric.
     Met_5		 : coefficient 5 of symmetric metric.

              Met_0 Met_1 Met_2
     Metric = Met_1 Met_3 Met_4
              Met_2 Met_4 Met_5

In the above description, the parentheses ( ... ) are for grouping, the brackets [ ... ] enclose items in a loop, and braces { ... } enclose items in a single logical record.

The metric, Metric, must have real, non-zero eigenvalues and eigenvectors at each node. The data may be written out or read in using records the length of loops or of the individual data items. Data items may be written out in free format of any specific form. MNODE files must be formatted ASCII.
