DOPR5 Updates design sensitivity tables
Updates design sensitivity tables.
Format:
DOPR5 XINIT,EPTTAB*,PROPI*,DESTAB,DTOS2K*,DTOS4K,
TABDEQ,DELBSH,GEOM4,DESGID/
DTOS2*,DTOS4,DELBSX/
STPSCL/S,N,RGSENS/PROTYP $
Input Data Blocks:
XINIT Matrix of initial values of the design variables.
EPTTAB* Family of tables of designed property attributes.
PROPI* Family of matrices of initial property values.
DESTAB Table of design variable attributes.
DTOS2K* Family of tables which are the same as DTOS2J* except that the dvid in
each entry refers to the position of an internal design variable ID in the
first TABDEQ record.
DTOS4K Same as DTOS4J except that the ID in each five-word entry is the
position of an internal design variable ID in the first TABDEQ record.
TABDEQ Table of unique design variable identification numbers.
DELBSH Matrix of finite difference shape step sizes.
GEOM4 Table of Bulk Data entry images related to constraints, degree-offreedom
membership and rigid element connectivity.
DESGID Table of designed grid coordinate attributes.
Output Data Blocks:
DTOS2* Family of tables which are the same as DTOS2K* except that the PREF
in each entry is the product of a DPLDXI element and the
corresponding design variable value.
DTOS4 Same as DTOS4K except that the last three words in each entry contains
the product of those in DTOS4K and the shape step size.
DELBSX Updated DELBSH where the numerical zero terms are replaced by a
prescribed small value.
