Fan Component P-Q results not matching with input.
Hello experts, my pressure drop value (56.21Pa) isn't matching the appropriate ones in the input P-Q curve (64.16) despite the solution converging. I have attached documents for your reference. Need assistance in figuring this out. Thank you.

Yes, they are the pressure from fan volume's inlet and outlet surfaces. The thickness of volume & direction is specified appropriately.
I have tried refining the mesh and boundary layer too, still there is a significant error in the pressure drop.
Thank you.

I ask that because I just went through the related tutorial ACU-T5101 and it behaves as expected.

I'm assuming your plot is showing pressure from "Fan Outlet" and "Fan Inlet" - the two 'ends' of the centrally-located fan volume. Is that correct? Is the thickness of that volume in the flow direction 0.032 as specified in the input file? The fan-component is assigned at the inlet surface to the fan. Is that how it was defined? (The input file has the direction indicated as -Z, so the main flow direction should be -Z.) There would also be some level of dependency on the mesh resolution.
Are you able to attach the model?
