When Abaqus/CAE generates a tetrahedral mesh, it first creates a boundary mesh of triangles on the exterior faces of the solid region and then generates the tetrahedral mesh using the triangles as faces of the exterior tetrahedral elements. When you assign adaptive remeshing to a solid region, Abaqus/CAE applies adaptive remeshing to the boundary mesh of triangles on the exterior faces. For more information, see Free meshing with triangular and tetrahedral elements. If Abaqus/CAE is using the mapped meshing technique in a region you have selected for adaptive remeshing, the mesh resizing algorithm may be slow to converge and require more remeshing iterations to achieve a given target error. To prevent Abaqus/CAE from using mapped meshing, you can toggle off Use mapped meshing where appropriate in the Mesh Controls dialog box. For more information, see Setting the mesh algorithm. |
