Negative inlet pressure
 

Hi all having trouble with a college project. When I go to measure the pressure at the inlet it comes out as neg which is wrong because then the fluid would flow from the 0 Pa outlet to the neg press inlet which is opp to what happens. Here is a dropbox link to the files please have a look and maybe you know what's wrong.
