Wrong sign in equation regarding thermal creep in Maxwell boundary condition
Hello.
Could you please check the sign in equation regarding thermal creep in Maxwell boundary condition? According to the literature (for example, file colin.pdf, page 32, eq. 2.58), in the code below it should be "+=", and in code line in maxwellSlipUFvPatchVelocityField.C, it is "-=", as you can see.
refValue() -= 3.0pnu/(4.0pT)transform(I - nn, gradpT);
