How to determine the Centre of rotation in Abaqus/CAE

[abubulina]

I need to determine the centre of rotation of the head of the femur and acetabular bones using Abaqus.
How can I find the centre of rotation for a sphere and a concave surface (the head of the femur and acetabulum bones) in Solid Edge?
Also I need to find the anatomical line of the femur which is the line passing through the centre on the femur.
Thank you.

Inspect, Physical properties might do it for you, you'll need density of the bone etc. and may need to assume constant density - that or model the bone as multiple parts.

Dear Kenat,

Thank you for your answer. Could you please expand a bit more on that (I am not yet proficient with Abaqus). To be more specific:
I need to find anatomical axis of the femur (midline), different angles for acetabulum and cetre of rotation of the femoral joint. The purpose of this is to position the implants into the bones in a logical manner (create correct axis and move the implants using assembly constraints rather than chaotic step by step translation and rotation). Is that possible in Abaqus or I need another software? I hope I make sense.
Any help/advice is much appreciated.
Best wishes,
A

You said:

However, I think I misread your question, the answer I gave you was for center of mass/volume etc. which isn't actually what you asked, sorry.

No worries. Thanks for trying.
