![]() For more information, see What is mapped meshing?, and When can Abaqus/CAE apply mapped meshing?. (Mapped meshing is the same as structured meshing but applies only to four-sided regions.) Abaqus/CAE determines whether it is appropriate to replace the advancing front algorithm with mapped meshing on any of the faces that belong to the source side. ![]() If you select the advancing front algorithm, Abaqus/CAE will use mapped meshing, if it is appropriate, to improve the mesh for some regions. For more information, see What is the difference between the medial axis algorithm and the advancing front algorithm?, and Free meshing with quadrilateral and quadrilateral-dominated elements. ( Abaqus/CAE generates hexahedral and hexahedral-dominated meshes by sweeping the quadrilateral and quadrilateral-dominated elements generated by the two algorithms from the source side to the target side.) However, if the region to be meshed contains virtual topology, you can use only the advancing front algorithm to generate the swept mesh. You can choose between the medial axis and advancing front meshing algorithms when you mesh a solid region with hexahedral or hexahedral-dominated elements using the swept meshing technique. To generate the preliminary two-dimensional mesh on the source side, Abaqus/CAE uses the free meshing technique with the Quad, Quad-dominated, or Tri element shape option, respectively. If a region is swept meshable, Abaqus/CAE can generate the swept mesh on a region that has been assigned the Hex, Hex-dominated, or Wedge element shape option. The revolved swept meshing technique sweeps the mesh on the source side along a circular edge.
