Implementation of maxwell slip velocity and Temperature jump with openfoam
 
I want to Run supersonic flow of air over a cylinder at Knudsen number Kn=.01
And therefore, I must to use Maxwell’s velocity slip and Smoluwski temperature
jump conditions at the wall boundary.

I see these condition in openFoam classes as :

Foam::maxwellSlipUFvPatchVectorField
Foam::smoluchowskiJumpTFvPatchScalarField

i use these boundary as follow:

type maxwellSlipU;
accommodationCoeff .5;
Uwall uniform (0 0 0);
thermalCreep on;
curvature on;
value uniform (0 0 0);
refValue uniform (0 0 0);
valueFraction .5

but i encounter this error

for solve this error what i must do ?

Hi dear foamer
 
I have same problem as you nowadays Could you help me to implement this boundary conditions ? Thanks a lot in advance. Best regards.
