ANSYS SpaceClaim 2021R1 STL convert to Geometry Part 2

If autoskin does not work fully can you combine the Patch body and manual skin surfaces ?

Hello, I'm working on a wrist reconstruction and I would like to know how it is possible to make or add ligaments or cartilages with Spaceclaim, I couldn't find the part 3 you mentioned so I guess you don't. didn't come out and the first 2 were very clear so I was curious how to do it

[@ansysfeaexamples9351]

Yes, it is possible to have cartilage between the bones. It is simply a matter of having the CT data segmented for cartilage instead of bone, then convert the STL into geometry. Ligaments are sometimes represented as springs.

@@ansysfeaexamples9351 Thank you for your answer, I had seen mentions of the springs but I was wondering if they were designed as classic springs or is it specific in the context

[@ansysfeaexamples9351]

@@nathancollard9591 It can be a classic spring if the line of action is simply between the end points. If the line of action has to wrap around a bone, then you need a flexible body to do that then use a spring after that.

@@ansysfeaexamples9351 Thank you very much, now that I have finished the ligaments I am asked for the cartilage, you rather said that CT scans were needed, is that the only solution? I had thought of doing a Boolean operation between 2 shells but the result is not satisfactory

@@nathancollard9591 You could create a disc of material about the right diameter but much too thick and subtract where the bone intersects the disc to make an approximation of the cartilage.

Can i use this model for my research paper??

[@ansysfeaexamples9351]

Yes you can.

Thank you sir

Sir could you send your name so I can mention it in my analysis paper
