 July 31, 2009, 03:20 nonuniform velocity at the inlet #1 New Member   andrianomena Join Date: Mar 2009 Location: madagascar Posts: 23 Rep Power: 9 Hi there, It's been a while, I'm actually implementing boundary condition of the velocity at the inlet,the thing is that the velocity at the inlet is nonuniform in fact for my case, the inlet is split into three portions and each portion has its own velocity,here what I tried: inlet { type fixedvalue; value nonuniform 100 ( ...... ) } But it didnt work!!! for more information, the field is rectangular with 100*50 cells the width contains 50 cells the length contains 100 cells and inlet is along the length. Can anybody help me out?Please Best Regards!

Try Code: ```inlet { type fixedValue; value nonuniform List 100( (0 0 0) ... ); }``` Remark: OpenFOAM usually provides info about the reason it is not working. Please add it to the post, it helps the others to give you the solution to your problem.... And not a guess like I just have done.
