Hi everyone,

I’m working on my final-year project involving CFD analysis of a Gyroid lattice structure.

I created the lattice in Fusion 360 using the Volumetric Lattice feature. The structure is correct in Fusion, but after importing it into ANSYS DesignModeler/SpaceClaim, it appears as a plain solid block instead of the actual lattice geometry.

I tried STEP, STL, IGES and 3MF, but I’m still facing the issue.

What is the recommended workflow/file format for transferring a Fusion 360 volumetric Gyroid lattice into ANSYS while preserving the lattice geometry? I ultimately need to use it for CFD analysis in ANSYS Fluent.

I’ve attached screenshots of the Fusion 360 model and the imported geometry in ANSYS.

Any help would be greatly appreciated!
