To help diagnosis of diseases of the circulatory, we have developed the system to perform computational mechanical approach. We have designed so that the system will be based on "Weak Coupling". So the system has capability to be improved easily in the future.This system performs five subsystems: voxel generation, fluid analysis, define loads, construct elastic wall, structure analysis, and volume morphing.By using this system, we analyzed an interaction between flow and structure in actual blood vessel from Computer Tomography (CT) image of real patient. The blood vessel we computed was coronary artery stenosis from actual patient image of CT, and we used pulsation inflow condition. A swirl generation and degeneration according to the inflow pulsation was found. And we qualitatively confirmed that the system has ability to handle Fluid-Structure-Interaction (FSI) by observing tube deformation according to flow pulsation.
