Hello Friends!
I come with a little doubt.
I'm trying to simulate an axial flow compressor using a blade to blade passage.
I impose mass flow at the inlet but I don't understand what does "value uniform (0 0 0)" mean. The axial direction of my domian is on the x-axis, so my Inlet patch is normal to the x-axis. Hope your help and thank you so much!

The "value"-Entry is only a dummy, because boundary conditions are programmed in such a way that they need the "value"-Entry in every case.


So you can just ignore it in this case. Maybe the "value"-Entry is used in the first time-step as an initial condition, but this should not have big impact.

Somebody please correct me if i'm wrong

Thank you so much!!! So, if my mass flow is 64.15 kg/s I can set value uniform (0 0 0) without problem?

Yes, think of it like "initialize with zero, overwrite with xyz".
