6th order polynomial equation as pressure load

Hi,

I have fitted a 6th order polynomial to a set of points and I want to use it as a pressure equation on one face of a propeller blade. The exact equation i'm writing in the box next to equation is this one:
-1.0157e(-16)*y^6+1.0721e(-13)*y^5-4.1705e(-11)*y^4+6.6163e(-09)*y^3-2.5475e(-07)*y^2-8.5948e(-06)*y+1.2454e(-03)

which has a maximum value of 0.0036 in the interval (0,350)

My model is in mm, RHO=2.781e-9 and E=70,000 so I think using MPa is consistent but I get 0 displacement and 0 errors

what's the problem?

I'm attaching a screenshot with my pressure load settings
