i'm having some boundary condition issues and i thought i might bounce what i've got now off some people.
i have 4 types of elements in a fairly asymmetric, complex mesh.
1) walls. nothing in or out.
currently pd is set zeroGraidnet, internalField 101325. U is set fixedValue, uniform (0 0 0), internalField uniform (0 0 0)
2) atmosphere (101.3kPa).
currently pd is set totalPressure, uniform 101325. this isn't good for me because i dont want them to be statically defined. U is set pressureInletOutletVelocity, uniform (0 0 0)
3) low pressure inlet (<101.3kPa), where i set the pressure explicitly in my dictionary pd.
currently pd is set totalPressure, uniform 1333.22 (~10 Torr), U is set pressureInletOutletVelocity, uniform (0 0 0);
4) gas inlet, where i set the velocity explicitly in my dictionary U.
pd is set zeroGradient, U is set fixedValue uniform (80.3007 -114.681 0).
are these appropriate? i'm currently using interFoam and i don't have much confiendence in these settings given the solutions i'm seeing.
any advice would be welcome.
