Castle is on a distinguished road
I am new to CAE, start with Rad pressure drop simulation and would like to correlate to physical result, but my simulation result always lower than the physical result.

I tried increase the number of prism layers from 2 to 8, result increase a little but not too much. screen shot is the physical models i used, also simulation I set up this one inlet and one outlet, set constant inlet flow and 0 KPA for outlet

Does anyone could point out which I need to look into and change the value or any wrong on physical?
