Knudsen Number

Dear,
I would need a post-processing tool like Mach for the Knudsen number. I was searching how to obtain dynamic viscosity (if Kn:=const*Ma/Re) for the calculation of Reynolds number for the compressible flow, but wasn't able to find any good example. The question is which object stores the sutherlandTransport.mu(thermo->T) reference and how do I initialise it. I was looking in the applications/utilities/postProcessing/velocityField/Mach example and there is almost all I need, except the access to dynamic viscosity (I use sutherlandTransport model for the pure nitrogen gas). Can please someone help me to construct this tool. Thanks for help in advance. Best, Sandro |

I did something, but the characteristic length scale has to be moved into the dictionary. Now I take it as an internal constant. Source should be in attach.
