| Outline of Final Research Achievements |
We have developed a new homogenization method to improve the accuracy of finite element analysis using unfitted mesh. The homogenization method appropriately determines the material constant at unfitted element as tensor, and thereby provides the solution that mathematically coincides with the exact solution when the fields are uniform. We developed a theory to handle anisotropic and nonlinear media appropriately and developed a fast analysis method by combining with the multi grid method. Moreover, we also conducted theoretical analysis from the viewpoint of generalized finite element method.
