Is it possible to do a segmentation of the lumbar spine from CT-data and use the 3D model (.igs) for further finite element analysis in ABAQUS or FEBio?

Thank you very much for your help. I finally created a volumetric model of the vertebra with the following adjustmens:

1. Wrap solidify module → Carve holes: 1mm
2. Smoothing → Closing(fill holes): 1mm
3. Gaussian Filter: 1mm
   The result looks like that:
   
   

but the problem now is, if I want to mesh it, I get a very edged and reduced model. I tried different paramaters and this seems the best (but still not good enough): scale= 3; multiplier=1; grading=5

Any idea, what I am doing wrong or what I should improve?
