Hello!
I want to model an air flow in a duct with a steel grid inside so that I can observe the influence of the grid. I apply a pressure at the inlet and outlet. I modeled the grid with designmodeler. And I made a 2000 mm extrusion of a square that covers the grid, this extrusion represents the fluid. The fluid and the grid are well separated. When I do a simulation with Fluent, there is absolutely no difference with the case without the grid for the value of the static pressure at the output... I join you some pictures Could you help me please? |

By any chance, have you a suggestion? Maybe I have to do an interface? Or consider the grill as a porous medium?
How I have to do to consider an obstacle against a flow in a duct? |

If you set inlet and outlet pressures means that you already know what you're searching.... Daniele |

Hello, thanks for your reply.
I have to put an inlet pressure and outlet pressure so that I can observe the evolution of pressure in the duct, especially before and after the grill. But that's okay, I have changed the modelisation of my grill and it's much better. Thank you anyway ! |
