Question

generative design to simulate

Hi,

 

I'm testing/evaluating the generative design extension in Creo 9.0 for our company. While it seems to work really well, I have issues generating a model out of it and related issues pushing it to Creo Simulate for detailed analysis. When generating the geometry part, when it kind of works, the program creates small edges and or surfaces that may be free floating, not connected along all its edges, same goes for vertices. This has happened on several parts now and furthermore, when the part is generated without errors, and I try to push it to Creo Simulate for further detailed structural analysis, more miniscule surface, edge or vertex errors are found, which prevents further analysis. Anyone experiencing similar issues and have functioning workarounds for it?

Hi Erik,

 

There are a handful of best practices that can help ensure that the geometry can be reconstructed for downstream analysis. Are you able to share any of the models that are giving you trouble (if you can't share them here, perhaps you can open a Tech Support ticket)? It would definitely help get an understanding of what might be going wrong. Also, feel free to message me directly, as I'd be happy to have a quick call with you to take a closer look, though having an actual model would always be the most helpful.

    Hi, just wondering if there was any follow up from this? I'm also experiencing the same issue whilst evaluating the GTO extension and would be interested in hearing what the best practices are to ensure geometries can be reconstructed downstream.

    Hi. My solution takes time but it works. So what I do is that I go into the "Reconstruction Shapes" and adjust the edges, faces and points so that the original shapes are covered. In some complex areas I delete edges and/or faces and then join the open edges again to close the holes. This simplifies the surfaces. This ensures that you get a solid object. Then I extrude away 0.5mm or whatever is necessary to remove the double folded surfaces and extrude it back, giving a clean interface.
