FIGURE 15.6
Mesh convergence study where the solution for displacement and pressure is compared at
several distances from the deformation source at increasing mesh resolutions. The goal is to
define a solution independent mesh resolution which ensures numerical fidelity.
More surgically relevant simulations of pig brain interventions are also
under way. Figure 15.9 illustrates the sequence of events needed to model tis-
sue retraction. First, the geometry of the retractor blade is predefined as a wire-
frame description which can be inserted into the model in an arbitrary location
