February 14, 2018, 16:56	1D to 3D boundary conditions	#1
acalado Senior Member André Join Date: Mar 2016 Posts: 133 Rep Power: 10	So I am attempting to model a tunnel network, and I have some results from a 1D software that I intend to use as boundary conditions in Fluent. My problem is I only have mass flow (velocity) from the 1D model, and I need to match these flows for each inlet/outlet boundary condition. I can put all but one boundaries as velocity inlets, but the remaining one (pressure?) must match the 1D results. Thanks for any help and insights! __________________ Sapere aude!
