Hello

In the equation for internal energy in sonicFoam.C, we have on the left hand side:
// rate of change
fvm::ddt(rho, e)
// convection
+ fvm::div(phi, e)
// conduction
- fvm::laplacian(mu, e)

In this last term, mu is it the viscosity, or should there be some kind of heat diffusion coefficient (kappa) ?

Best regards
Thanks in advance

Hi, Stijn

see, how the variable 'mu' is defined. I mean to say that check the dimenions of tha variable...
