Product: Abaqus/CAE
Benefits: When you create a tetrahedral mesh for solid regions, Abaqus/CAE first creates a surface mesh of triangular elements and then uses this mesh to fill the solid with tetrahedral elements. The tetrahedral meshing process has been enhanced with changes to both the initial surface mesh and the resulting tetrahedral mesh. The enhancements improve the mesh quality, memory use, and processing requirements of the tetrahedral meshing process.
Description: Several enhancements have been made to improve the robustness of both the triangular surface mesh and the resulting tetrahedral mesh. The enhancements do not change the user interface; however, they improve the speed, memory use, and success rate of tetrahedral meshing, especially when meshing large or complex parts. Some of the enhancements include reducing potential folded mesh errors, excessive loss of curvature, and mesh intersections in the triangular mesh. In addition, the default quadratic tetrahedral element for Abaqus/Standard in the Element Type dialog box has been changed from C3D10M to C3D10.
