Hi,
When it is export in INP. format from 3-matic, it does create extra surface. What you need to do is delete the nodal surface in your INP files.

Hi,
I have done the hip replacement analysis before and i am happy to send my femur model which is already meshed and it has 10 parts.
I suggest you to use 3-matics software in order to refine mesh and exports femur model in INP format.
