Software tools for automatic generation of finite element mesh and application of biomechanical calculation in medicine

Abstract

Cardiovascular diseases are common and a special difficulty in their curing is diagnostics. Modern medical instruments can provide data that is much more adequate for computer modeling. Computer simulations of blood flow through the cardiovascular organs give powerful advantages to scientists today. The motivation for this work is raw data that our Center recently received from the University Clinical center in Heidelberg from a multislice CT scanner. In this work raw data from CT scanner was used for creating a 3D model of the aorta. In this process we used Gmsh, TetGen (Hang Si) as well as our own software tools, and the result was the 8-node (brick) mesh on which the calculation was run. The results obtained were very satisfactory so...
