Variable inlet size with only one mesh

My case consists on a box 10x10x10 with 4 outlets (one each side at the botton) and on inlet in the center of the box top.
The problem is that i have serveral sizes of inlet to test (0.16m²,0.25m²...2m²). I did one mesh with several blocks and all the outlets, but the inlet is not specified. Can i use this mesh with the bigger inlet surface and do all simulations just changing the inlet variable/function at the top? It will be like a 2m² inlet, but in one simulation just 0.16m² will have an airflow and so on. Is it possible? Thanks |

Is it an inlet or not?

I created an inlet with 1m², i did the simulation and its everything working.
Now i want to change the inlet to 0.75m² and later 0.5m², 0.2m² and 0.16m². Is there a way to do this without changing the mesh? like a function that specifies 0.5m² with a velocity and the rest of the inlet with 0 velocity. thanks |

Otherwise you will have to change the mesh. There is even a way of making a parametric mesh with the m4 preprocessor. The input to the m4 could be your inlet size.
