Pelvic floor models (in sagittal view) for finite element analysis. A Anatomical model (cyan colour, superimposed on the muscles of the pelvic floor, which are shown in red), oriented approximately along the pubococcygeal axis of an upright person. B Flat, ellipsoid and anatomical models (sagittal views). In the left column the three models are shown before loading, whereas the right column shows the displacement in response to 4 kPa pressure. The rainbow colour scheme indicates the magnitude of the maximum displacement of the model elements. Blue corresponds to no displacement, red to high displacement
