Hi everybody!
I'd like to ask for help in ICEM CFD. I've just started my PhD and began to build mesh for calculation. I am trying to simulate a 3D hydrogen release and jet-fire in an enclosure in Fluent, but first I need to build mesh in ICEM CFD 13. The geometry is the cube enclosure 1x1x1m3 with wall thickness 0.02m, which is in the centre of the outside environment of hemispherical shape. In the centre of this cube there is an inlet pipe for release. On the side wall of the cube there is a vent opening which is near the ceiling. I’ll try to describe the problem which I faced. First I did all tutorials, but still no idea of how to block that geometry such that in different places I’ll have the exact mesh size. There are four zones with different sizes: pipe, vent opening, walls of the cube, space inside of the hemisphere. Each of them should be differing in mesh finest. I have to built hexahedral mesh which will increase its size from pipe to cube wall, in wall should be another mesh size for heat transfer, as well as vent opening with more finest mesh inside, mesh for the hemisphere should have the biggest size. Geometry is attached. Could you tell me please where can I find relevant information on how to do this? I will really appreciate your help. |
