DOPTPRM, LATLB

Bulk Data Entry This parameter is used to control the Automatic Reanalysis process at the end of Phase 1 in Lattice Optimization.

Parameter Values Description
LATLB <AUTO, USER or CHECK> This parameter is used to control the Automatic Reanalysis process at the end of Phase 1 in Lattice Optimization.
AUTO
Turns ON the Automatic Reanalysis Process.
USER (Default)
Turns OFF the Automatic Reanalysis Process and the user-defined LB value (or default of 0.1) is used to generate Lattice Structures for Phase 2.
CHECK
This option can be used to run a single reanalysis iteration and a warning will be output which contains the percentage difference in compliance between the original and the reanalyzed structure. The CHECK option can be used to gain information about the compliance performance of the structure using the specified LB. If the compliance performance is not as expected, then you may consider rerunning Phase 1 using AUTO to possibly find a better density Lower Bound (LB).
