Processing of User Errors
1.9 Processing of User Errors
Modules used in Phase I of the superelement SOLution sequences (SOLs 101 through
200) include an option to continue processing after fatal errors are discovered and
printed in the output file. The module completes processing as best it can and then sets
a special integer parameter named NOGO to -1. The output files may be purged or
incomplete. If no errors are discovered, NOGO is set to 0. The DMAP writer can
choose to branch to the end of a loop or take other actions when error conditions are
discovered. This option is selected by setting SYSTEM cell 82 to 1. Users who insert
alters into Phase l should be aware of this option.
An example of this option, based on the method used in SOLs 101 through 200, is:
PUTSYS(1,82) $ALLOWS DMAP TO FIELD NOGO FLAGS
.
.
.
GP2 GEOM2S,EQEXINS,,GEOM2A,EPTA/ECTS,ECTAS $
IF ( NOGO = -1 ) THEN $
CALL ERRPH1 //SUBDMAP/0/-1/DUMMY $ LOOPER
RETURN $ CONTINUE TO NEXT SE ALTHOUGH
ENDIF $ ERROR FOUND IN CURRENT SE
.
.
.
PUTSYS (0,82) $ DISALLOWS DMAP TO FIELD NOGO FLAGS
The GEOM2S file contains element connectivity data. If the GP2 module detects errors
in this data, it will set NOGO to -1.
Modules that presently have this option include:
DCMP MGEN
DECOMP MTRXIN
DYCNTRL SEDR
EMG SELA
GP2 SEMA
GP3 SSG1
GP4 TA1
LCGEN
