Create polyhedral mesh in ANSYS Mesh

CFD10111 · August 31, 2022, 10:20

Hi,

I can't find the option to create a polyhedral mesh in ANSYS Mesh (note, this is not ANSYS Fluent). I chose CFX as my solver. So far my mesh has automatically been generated as hexahedrals. Any suggestions would be much appreciated.

Thank you!

Ansys Meshing cannot create a polyhedral element mesh. The mesh methods are listed in the User Guide at: help/wb_msh/msh_types_shape.html.

CFX will create its own dual mesh of polyhedra elements from the tetra/hexa/prism/(maybe pyramids) elements.

If you want a polyhedral element mesh then you will need to use Fluent Meshing and solve within Fluent.

Put this in the https://www.cfd-online.com/Forums/ansys-meshing/ forum might get you more help.

I see, that makes a lot of sense now. Thank you!!
