Dear all,

I have a question.
I was unable to calculate the grad U using the postProcess utility of interFoam in OpenFoam 4.1 because I had an error that I could not fix it. Although it seems to be very frequent, I did not understand how to fix it.
However, in order to obtain the gradients of velocity, I used the filter in paraView "GradientOfUnstructuratedDataSet".

I was wondering if somebody has used it0 to calculate the shaer stresses ?
Because I am a bit confused about the dimensions.
The gradients should be [1/s] and to obtain the shear stress I should multiply it for the dinamic visosity mu. Is that right ?

Thank you in advance for your help.
