Hi,

Yes, I've modified the code in 1.7.1 a little bit, but it's just in UEqns.H and twoPhaseEulerFoam.C, and I've tried to print out the rUaAf in pEqn.H. it's not zero, but in alphaEqn.H, it's...

It turns out they added #include "pimpleControl.H"

Hi,

I've installed the openFOAM-2.0.1, and had a look at the twoPhaseEulerFoam, it turns out that they are using p.storePrevIter() to store the information obtained in pEqn, which has solved my...

Hi Alberto,

Yeah, I'm using 1.7.1, maybe that's the reason. I'll try to implement 2.0, and see what's the difference.

Hi Alberto,

I'm sorry to bother again.

actually, I did as you code in the alphaEqn, and compile using Allwmake, and the result is still like this:

Hi Alberto,

Thanks for your patient answer!

I agree that there must a numerical trick in alphaEqn. however, let's derive step by step, and focus on where there is g0>0.

first, in pEqn.H,...

Hi, Aberto

Thanks for your reply!
