Hello

I am trying to modelate a T-jet mixer and my problem is not converging.

I think the problem is in the mesh that i am using. I am doing that in Gambit 2.3.36. What is the best mesh type that i should use?

Near the end, i am usen a Hexahedral/Wegde Cooper mesh, to align the flow. Near the impingement point, i am using a Tet/Hybrid mesh. I am using Hexa core, since it will use Hexahedral elements in the center, and Wegde, tetra and pyramidal surround it.

My doubt is

What is the best element Hexahedral only or Hexahedral with Wegde elements for the cooper? And for the impingement zone, should i use Tgrid or Hexa Corte?

Thank for the answer and for the time
