Description

DISCRETE

Real > 0.0

Defaults

1.0 – general default.

2.0 - for solid dominant structures with member size control and no manufacturing constraints.

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