Hi Everyone,
I am trying to simulate a water lubricated bearing on CFX. With that in mind, I want to take into consideration the viscosity variation with temperature. The attached photo shows the relation between the kinematic viscosity [cSt] and Temperature [K]. I would like to import this formula into CFX, and I tried writing an expression, but without any success.

Can anyone explain to me on how do that please?

Note:
a, n, and m are constants.

Thank you very much in advance!
