Hello,
I have a test.geom file to generate a structured hexahedron mesh. If I run gmsh with this option -order 1 I get what I expect that is to say hexadrons with 8 nodes. When I use the option -order 2 I get hexahedrons with 20 nodes. How can I get hexahedrons with 27 nodes ? Thanks a lot |

In case you didn't notice the gmsh manpage, it describes where all these nodes are located: http://www.manpagez.com/info/gmsh/gm....0/gmsh_60.php Or just google for second-order hexahedron (that's how I found the above manpage), I'm sure you will find something useful there. If not, you'll have to switch to a FEM forum where the people would know something about these types of shape functions. |
