Lattice structure minimum diameter

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!

Hi,

You can set a Maximum Radii using MAXRAD.

I dont see a way for minimum radius, but I will check if there is a way to work it out.

Hello

Thank you!

Well the minimum diameter is also related to the element size. I guess by setting a mesh with enough big elements, will create bigger lattice structures.

How does the MINDIM work?

I have changed the elment mesh size to 7.5 mm and set MINDIM to 0.5 mm. But I still get lattice structures with smaller diameters (Ømin=0.038 mm).

Hi,

I dont think MINDIM will help as MINDIM should be set to 3 times the element size.

I will check with devs regarding the same and will let you know soon.
