DOPTPRM, DISCRETE

Bulk Data Entry Discreteness parameter. Influences the tendency for elements in a topology optimization to converge to a material density of 0 or 1.

Definitions

Parameter Values Description
DISCRETE Real ≥ 0.0
Defaults:
1.0
general default
2.0
for solid dominant structures with member size control and no manufacturing constraints
Higher values decrease the number of elements that remain between 0 and 1.
Note: Recommended bounds are 0.0 and 2.0 for shells, or 3.0 for solids.
