MATMOD
Matrix modification
Input Data Blocks:
GEOM3 Table of Bulk Data entry images related to static and thermal
loads.
GPL External grid/scalar point identification number list.
UG Temperature matrix in g-set.
Output Data Block:
GEOM3T GEOM3 table with new or modified temperatures.
Parameter:
SID Input-integer. Temperature set to be modified or added.
Remarks:
1. This option should only be used in heat transfer analysis.
2. None of the data blocks may be purged.
3. Only grid temperature records (not elements) are modified.
Example:
Put data from the temperature vector UG into a record for SID = 30.
MATMOD GEOM3,GPL,UG,,,/GEOM3NEW,/18/30 $
Option P1 = 19
Extract a temperature vector from a GEOM3 table.
Format:
MATMOD GEOM3,EQEXIN,,,,/UGT,/19/SID
Input Data Blocks:
GEOM3 Table of Bulk Data entry images related to static and thermal
loads.
EQEXIN Equivalence table between external and internal grid/scalar
identification numbers.
Output Data Block:
UGT Updated temperature matrix in g-set.
Parameter:
SID Input-integer. Temperature set to extract.
