Hi,

I'm currently conducting flow simulation using an axial fan. I fed in the fan curve input from the vendor and conducted the study. 

Why is the operating point always at the same location (closed to no flow) even i change the geometry? 

My aim is to find the actual operating point of the fan based on pressure difference in the system. There are flow obstructions in the system, so does pressure differences.
