OptiStruct

Lattice structure minimum diameter

Recommended Posts

Hello

 

Normally a lattice optimization does create lattice structures of different elements. Does a way exist to set a minium diameter of the lattice structure?

I know the function 'MINRAD', which cleans in the second optimization phase and eliminates all elements above the set value. If I use MINRAD, almost all  lattice structures are eliminated, as they are quite small (between 0.0027 and 0.335 mm). The ideal lattice structure would have diameters above 0.5 or 1 mm. How can this be set?

 

I thank you in advance for your help!
