[GAMBIT] O Grid

zainab · July 27, 2012, 14:47

Welcome
I need some help about the (O Grid) mesh in Gambit, I do not have any idea about it, I wont it for meshing a cylinder of length 5.83m and 25.4mm diameter. thanks.

You need to create five domains with square in center.

Hi Far and thank you for support, but apologize me, I don`t understand yet, please, tell me more about O Grid, in Gambit, or at least what is the steps of doing this type of mesh.

Hi Far
I need your help if you can? I want to do a grid refinement, for a 3D cylindrical pipe of hexahedral cells, to fine the mesh near the pipe wall to get the slug gas-liquid phase distribution. what type must I do? Boundary, region or Gradient?

Hi guys, i have to simulate a wind turbine rotor in fluent using Gambit, I need to do a methodology, i mean explain step by step what i'm doing and for example why I choose one model of turbulence or another, why I do this mesh type or another, I really worried, because I´m confused, please if you know how to do it help me, and if you have information about diferents methods of simulation and meshing, i need it. :S

THANKS
