A Simplified Method for Conversion …

found that it is very easy to convert the surface model into solid model with the aid
of SolidWorks. The solid model can be further utilized in simulation software such
as ANSYS or Abaqus, to perform and calculate von Mises stress, strain as per the
researcher’s requirement. The suggested methodology will be very useful for the
researchers who are thinking to start their research in the field of spinal implantation.
Researchers can also perform the mesh sensitivity analysis to refine the results.
Moreover, the same procedure may be adopted to develop the other spinal region,
other body part surface and solid model.
