yassepid is on a distinguished road
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 :


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 ?
