We have proposed a CFD scheme using Helmholtz-element, which is based on Helmholtz's theorem and has many advantages to CFD: for example, the continuity condition can be satisfied algebraically. We apply voxel-elements to simplify to handle the system, since the basis function requires C_1-continuity. In this report, we propose a boundary fitting-technique for the voxel element applying patch system, which is constructed with eight elements (tour elements in 2D). The method is valid as a numerical integration technique of the physical domain such as FCM to keep high accuracy in general.
