Outline of Final Research Achievements

The purpose of the research is to visualize the stress distribution loaded on the aortic valve by using the simulation results for the blood flow and the opening/closing of the aortic valve, which are in the aorta that is the biggest blood vessel in our body. Then, we have generated simulation models with particle for both elastic body such as the aorta and the aortic valve, and fluid that is blood, and then performed the simulation of the blood flow and the opening/closing of the aortic valve by applying the governing equations of fluid with some arrangement to not only fluid but also elastic body. In addition, we have succeeded in visualization of the stress distribution loaded on the aortic valve with computer graphics by translating the tensor of the stress, which is obtained by the simulation, to a scalar.
