Fig. (14) The figure depicts the set-up and execution of test runs with isotropic parameters, for the ordinary manual segmentation model, the segmentation model using harmonic smoothing and the artificial geometric model respectively. The test load is 0.05 MPa and applied in the negative z-direction, on the intersection of the top face of the model, with a given cylinder. The fixed constraint is the intersection of the lower part the vertebrae with a user-defined lower cylinder. This type of test run will process faster than if we were to include 3 vertebrae and discs but will suffice to make clear whether or not a difference between isotropic and orthotropic modeling will render practically tangible different calculation times, and also whether or not the gap between meshing times compared to artificial geometric modeling applies also for calculation times. The result of the test run is displayed for the surface and also using slice planes.
