Table of design iteration history
2 CVTYP I Convergence type: 1=soft or 2=hard
3 CVPROV I Convergence result: 0=no, 1=soft, or
2=hard
4 OBJ1 RS Initial objective value
5 OBJO RS Final objective value
6 GMAX RS Maximum constraint value
7 IRMAX I Row of the maximum constraint value
8 XVAL RS Design variable value
Word 8 repeats until End of Record
Word Name Type Description
1 NDV I Number of design variables
2 UNDEF(5 ) none
Notes:
1. For soft convergence, the final objective and constraint values are those
obtained from DOM9.
2. For hard convergence, they are obtained from a re-analysis.
3. The design variable values are identical for soft and hard convergence and
are repeated for consistency.
