| Abstract: |
| This paper presents a parallel mesh deformation method for hybrid mesh, based on Vertex-Ball Spring Smoothing(VerBSS).The hybrid mesh's non-triangle/non-tetrahedron elements were decomposed into the triangle/tetrahedron elements in the specific template.For every internal node and its surrounding nodes, a corresponding sub-spring system was established.The spring system's subsidence problem was avoided by adding Ball-Vertex springs.One by one, all internal nodes were calculated.Its weak coupling is good for the parallelization of solving process.It only needs to section the virtual mesh in the process of parallelization.The complex geometric partitioning and different types of elements' incompatibility can be avoided in this method.For large-scale complex geometries, this method can significantly improve deformation efficiency and has a good adaptability. |
