[ANSYS Meshing] Create Hex mesh

mohsen_23 · October 5, 2017, 10:49

Hi every one
I want to create hex mesh on my geometry, but when I select multizone method suddenly mesh generation stopped and can not create mesh.
I use ansys meshing and there are some pics of my model.
Can anyone help me?
Thanks in Advance

Hi Mohsen,

Well "multizone" is not a magic mesh method that succeeds every time you use it and generates a nice hexa mesh. If it fails you need to help it a bit, like allowing free mesh type (tet / Hex dominant / Hexa core), manually pick source face, etc. Also play with the meshing parameters that are available like the element sizes, local refinements, size functions, relevance center etc ...

Have fun
