The governing equations for blood flow and their associated numerical methods are implemented as the core solver in the tool. Dedicated user interfaces are designed to configure the boundary conditions and visualize important flow parameters. The tool is tightly coupled with an open source 3D visualization software CMGUI, and delegates the pre and post processing tasks to it. As a modeling exercise, we solve the blood flow in an arterial tree of the human body which consists of 39 vessels and 19 bifurcations. We also simulate the flow pattern variations when a catheter is inserted into the arterial tree. |
