抄録

We proposed new computational method using Newton-Raphson method for elastic deformation problem by the fluid force in the previous paper. However, the jacobi matrix takes long computational time in that method. In this paper, we propose two new computational methods for jacobi matrix. One is the method that the jacobi matrix Is calculated using a local region of flow field. The other is the method that the jacobi matrix is calculated only from the boundary condition. The new methods shorten the computational time of jacobi matrix drastically. The flow in an elastic tube with a stenosis was calculated numerically as a computational example. The numerical results obtained by the present methods show good agreement with the results obtained by the previous method.
