hi there!
hope you all are doing well.

I am performing a simple fluid flow cfd simulation of chamber. where i want to see how air is flowing.

surprisingly, In result at inlet, i am getting 0 m/s but i applied 350m/s in velocity inlet boundary condition.

I've already run a lot of simulation; I was getting correct value of velocity.
but, from last couple of simulation i am getting wrong value.

please! share me your solution or thoughts,
your every word really means to me a lot.

sending positive vibe!
