Description

MATINIT

Real between 0.0 and 1.0

This parameter defines the initial material fraction. For Topology and Free-Size optimization runs with mass as the objective, default is 0.9. For runs with constrained mass, the default is reset to the constraint value. If mass is not the objective function and is not constrained, the default is 0.6.
