Default udf diffusivity in contour plot

Dear all,

I have got a problem with the contour plot of the result of the mass diffusivity of my species, which I calculated using the strain rate. I also use the strain rate to calculate the viscosity of my fluid via a udf and have no problems showing this for several planes using "contour plot".
For any reason, if I load a data file and try to plot the mass diffusivity in a plane it only shows me a constant value (for each plane the same), which ist the constant part of my diffusivity equation (see pic), but not the part which ist calculated using the strain rate. But if I record "monitor data" in the single planes, a value changing with the strain-rate can be seen.
If I make fluent calculate one more iteration, I receive a correct contour plot including the "strain-rate-part" (see pic). However, if I save this case&data now and reopen it, the proper contour-plot is gone again and only the constant value is shown.
Does anybody have any idea how to solve this problem?
Thank you in advance for any help!
