magnetic saturation results not matching experimental

I have been modeling an electric motor in 2d using perpendicular induction current mode (emqa). My low current results match my experimental results well. However, when I add satuation by selecting nonlinear material (soft iron MUR) the results do not match well. The effect of saturation is in the correct direction, but the effect is way too large. I tried putting in my own function for ur but the effect does not match the experimnental data (which has been verified)

The effect is to reduce the flux almost linearly with increasing current until the current. Then when the current is about 10x where experments say saturation begins the model begins to show saturation.

Does anyone have experience with this?
