Hi All, It appears that the quality of mesh generation depends on the version you use. I use Mesh.Algorithm3D = 1, and Mesh.Algorithm =5.
For example, if I use gmsh-3.0.3, I got Info : Opti : (7594757,0,400672) = 1.34590E+03 QBAD 6.40230E-03 QAVG 6.92222E-01 ( 650.191 sec) Info : Opti : (7649463,0,408083) = 1.34590E+03 QBAD 6.40230E-03 QAVG 6.92316E-01 ( 965.826 sec) Info : Opti : 4 ill-shaped tets are still in the mesh Info : Opti : 0.00 < QUAL < 0.10 : 7 elements I But if I use gmsh-3.0.6, I got Info : Opti : (7588653,0,400922) = 1.34590E+03 QBAD 1.05131E-02 QAVG 6.92189E-01 ( 561.789 sec) Info : Opti : (7643427,0,408262) = 1.34590E+03 QBAD 1.05131E-02 QAVG 6.92284E-01 ( 821.088 sec) Info : Opti : 4 ill-shaped tets are still in the mesh Info : Opti : 0.00 < QUAL < 0.10 : 5 elements I If I use the newest stable version gmsh-4.0.0, I got Info : Opti : (5126023,0,163893) = 1.34579E+03 QBAD 6.22727E-04 QAVG 7.99073E-01 ( 556.652 sec) Info : Opti : (5145672,0,165902) = 1.34579E+03 QBAD 6.22727E-04 QAVG 7.99114E-01 ( 772.064 sec) Info : Opti : 6 ill-shaped tets are still in the mesh Info : Opti : 0.00 < QUAL < 0.10 : 9 elements Although the newer version gave overall better quality, but it generated some very bad elements. Is there a way that I can improve the quality of the mesh, especially to eliminate the elements of poor quality? Thanks a lot for your help.
