the perturbed configuration for each load case and for each design variable.

Merges tables to evaluate responses for the perturbed
configuration
DSAE ESTDVP,ESTDVS,TABEVP,TABEVS,TABDEQ/
ESTDV2,TABEV2 $
ESTDVP EST with element property design variable perturbations.
ESTDVS EST with grid design variable perturbations.
TABEVP Cross-reference table between ESTDVP records and element and
design variable identification numbers.
TABEVS Cross reference table between ESTDVS records and element and design
variable identification numbers.
TABDEQ Table of unique design variable identification numbers.
ESTDV2 Merged EST with grid and element property design variable
perturbations.
TABEV2 Merged cross reference table of TABEVP and TABEVS.
Remarks:
1. TABEV2 is in the ascending alphanumeric EST sort. IVEIDs are assigned to
ensure that internal element IDs are unique and in ascending order.
2. For purposes of computational efficiency, the sizing design variables have been
split into two sets. The first set consists of those design variables which affect the
stiffness and mass matrices, e.g., cross-sectional area of rod, thickness of plate etc.
The second set consists of those variables which may affect the responses, but
have no effect on stiffness and mass matrices, e.g., recovery points in a beam or
plate.
