| Abstract: |
| An adaptive remeshing method with grid-based approach for hexahedral element mesh is presented, which is based on the geometric features of old mesh model and the physical field variables distribution of new mesh model. First, using adaptive remeshing method of hexahedral element mesh with grid-based approach, the base mesh is generated, whose density is controlled by boundary curvature and geometry feature of the old mesh model. Second, physical field variables are transformed from the old mesh into the new mesh. Finally, to reduce the analytical error of finite element, with the error estimating method for FEM, the error of new mesh elements are estimated and the elements with large error are refined. The effectiveness and robustness of the algorithm are tested through the applications. |
