MESH QUALITY IMPROVEMENT IN COMPUTER AIDED ENGINEERING |
摘要 |
A method, for use in meshing a CAD domain in a computer-aided design (CAD) or computer-aided engineering (CAE) system, comprises carrying out a procedure comprising: obtaining a set of mesh elements by extracting, from a previously-generated mesh of the CAD domain which has undergone a mesh element optimization process in respect of interior elements of the previously-generated mesh, mesh elements which do not satisfy a preselected mesh quality metric; decomposing the set of mesh elements into connected sub-meshes; carrying out a serial mesh element optimization process in respect of each sub-mesh independently and in parallel, under the condition that boundary nodes of sub-meshes are not moved, to obtain optimized sub-meshes; and obtaining an optimized mesh of the CAD domain by integrating the optimized sub-meshes into the previously-generated mesh. |

1. A method for use in meshing a CAD domain in a computer-aided design (CAD) or computer-aided engineering (CAE) system, which method comprises carrying out a procedure comprising:
obtaining a set of mesh elements by extracting, from a previously-generated mesh of the CAD domain which has undergone a mesh element optimization process in respect of interior elements of the previously-generated mesh, mesh elements which do not satisfy a preselected mesh quality metric; decomposing the set of mesh elements into connected sub-meshes; carrying out a serial mesh element optimization process in respect of each sub-mesh independently and in parallel, under the condition that boundary nodes of sub-meshes are not moved, to obtain optimized sub-meshes; and obtaining an optimized mesh of the CAD domain by integrating the optimized sub-meshes into the previously-generated mesh. |
