DOPTPRM, POROSITY
Bulk Data Entry Controls the amount of intermediate densities in the model in the first phase of the Lattice Structure Optimization run.
| Parameter | Values | Description |
|---|---|---|
| POROSITY | < HIGH, MED, LOW > | Controls the amount of
intermediate densities in the model in the first phase of the
Lattice Structure Optimization run. For lattice cells the
homogenized Young's modulus to density relationship is approximated
as E = ρPE0, where E0 denotes Young's modulus of the
dense material and P is the penalty value. Varying levels of
lattice/porous domains in topology results are controlled by the
parameter POROSITY which adjusts the penalty (P).
