I wanted to know which type of mesh would be suitable in ansys workbench to create a mesh of human bones (knee joint). I require a mesh type which also requires less computational power. Thank you for your help in advance.

If you make the bones hollow and leave out the very weak spongy center and only have geometry for the thin compact bone at the surface, you will have a large reduction in model size and the time to solve will be much less.
See the CT image of a knee in this post.

Is tetrahedron a good choice for the meshing the bones? As the bones have highly irregular surfaces, the hex dominant meshing was giving errors.

Peter, please correct me if I am wrong.

Yes, tetrahedral elements are okay for this mesh since the deformations will be small. Brick or hex meshing is very helpful when deformations are large such as with the incompressible rubber in this post.
Some researchers are using hex meshes.
