Optimization Post-Processing

[Rica23]

Hi everyone,

I am currently performing a design work on a rather complex geometry and have been using Abaqus/Tosca to perform the topology and shape optimization tasks. The results have been well connected geometries, despite the complexity. I am currently going through some issues, mostly due to my inexperience.

I need to proceed with a design interpretation of the optimization solution, but due to its complexity (and because I have other design to compare and also interpret), I was searching for the best method to do it and have a new solid to perform static analysis on Abaqus. My first approach was through PolyNURBs in Altair Inspire, but the complexity of the task somewhat put me off. My second approach was by fixing some of the issues with the resulting mesh in MeshMixer, and then use Rhino to create a quadmesh. I'm really happy with these results, but I'm not sure if there's any way to create a solid from these through an automated process. I've tried Fusion 360 but constantly run into issues, probably due to the lack of RAM (working with 16Gb).

So my question boils down to, is there any good alternative to the laborious work done with polyNURBSs? I'm guessing that using Inspire is my best option here, but I'd love to hear input from people that have a lot more experience than I do on whether there are better options to do this work.

Thank you!

So you want to recreate a complex geometry from the results of topology optimization, right ? I think that SpaceClaim might be a good choice for this purpose.

Yes, that's what I'm trying to accomplish. I'll take a look at SpaceClaim and see how it fits my needs. Thank you!
