How create a 3D structured mesh in a easy way without ICEM CFD?

      Hello everyone!


      So, here I have a convergent-divergent tube type, like a "venturi" and I want generate a structured mesh but I'm use academic package and I don't have ICEM CFD. I need a small height in the cells near wall, for this I try to use inflation layers but when I make this I get a unstructured mesh. If my domain were 2D I would use edges to imprint size controls, but as the domain is 3D I don't know how is the best/easy way to do this.


      Someone have some tips about it? 


      Thanks for helping,


      Mantovani.

      Hi Jose,


      Can you please try to use the Multizone plus inflation as shown in the video below?

      Hello Jose,


      I apologize, I did not read your question properly. I thought you were looking for a way to use ICEM CFD for getting your mesh. Please follow klu's advice and use Multizone to create your mesh. It is always a good practice to select the source and target faces for Multizone.


      Thank you.

      Try multizone with dedicated source and target as Kremella highlighted,
