DOPTPRM, OBJTOL

Bulk Data Entry Relative convergence criterion.

Definitions

Parameter	Values	Description
`OBJTOL`	Real > 0.0 Default = 0.005	If relative change in the objective function between two design iterations is less than `OBJTOL`, then optimization stops. A relative change in the objective function of 0.005 is the same as a 0.5% change in the objective function. For Lattice Structure Optimization, the default is set to 0.001.

Description

OBJTOL

Real > 0.0

Default = 0.005

If relative change in the objective function between two design iterations is less than OBJTOL, then optimization stops.

A relative change in the objective function of 0.005 is the same as a 0.5% change in the objective function.

For Lattice Structure Optimization, the default is set to 0.001.
