Hi

 

How to split tetrahedral element in a volume into four hexahedral elements?

Please see the attached figure. I know that Cubit can do that, I am wondering whether Hypermesh can do the same thing or not? (https://cubit.sandia.gov/public/13.2/help_manual/WebHelp/mesh_generation/meshing_schemes/conversion/thex.htm)

 

Thanks,

Attila

    Yeahn you can do that with Hypermesh too. See my screenshot.

    3D => split => solid elements

    Thank you! How is the performance of these hexahedrals? will they perform better than tetrahedrals?

    Personally, I never use this method because you always loss the quality with obtained hexa.
