Hi Fomers
At interFoam at some where there is:
rho==alpha1*rho1+(1-alpha1)*rho2
is == true or it must be
rho=alpha1*rho1+(1-alpha1)*rho2
?
Thanks
Best regards

Hi ata,

I had a similar finding in rhoSimpleFoam and got the answer that operator overloading is in place for comparisons...

The == in this case means that not only the cell values of the rhs is given to rho, but also the boundary conditions.
