although that I am quite "fresh" in OpenFoam, I found out that it is pretty powerful and it is gaining on popularity. But on the other hand I am missing the capability to use (prescribe) the combination of "zero gradient" and "mass flow rate" boundary conditions at inlets (or at outlets)! So, do you know someone that has already (or is willing and able) wrote down small piece of program for this? Unfortunately my knowledge in C++ is extremely low...
Of course one can overcome this by modeling long enough "inlet section"(but this can be quite "computer memory" consuming, especially for higher values of Re number) or by prescribing fully developed values for velocity, etc. (but this is known only for Newtonian as well as some basic non-Newtonian fluid models and not for Carreau-Yasuda or some other "industrially" interesting non-Newtonian models)!
Mass Flow Rate And Zero Gradient
Unfortunately, I am rather fresh to OpenFoam and C++ and therefore I kindly ask "is there anybody out there" that is willing to hear "my cry for help":).
Enjoy the day,
I have problem to define mass flow rate B.C too. Any suggestion will be appreciated.
