Upgrading a solver from OF 1.7.1 to OF 2.3.0
 

Hi Dear Foamers,

In fact, I have a solver which has been written based on OpenFOAM 1.7.1 and I want to upgrade that into OpenFOAM 2.3.

Could you please give me some advises how I could start to change?

It is possible for a person who is not professional in developing OpenFOAM solvers?

I would be appreciated if somebody give me some recommendations.

My suggestion would be to look for a similar solver in OpenFOAM 2.3 and see which part have changed.

Most likely, some of the included libraries have changed and some member function calls (most likely within the pressure corrector loop) have change. It is doable, but it really depends on the complexity of what was done within the solver.

If you can post the solver maybe others can give you a hand.

Cheers and good luck.

Thanks for your suggestion.

In fact, my solver is twoPhaseEulerFoam which has been coupled with population balance.

If I understood correctly, you meant I can compare twoPhaseEulerFoam in OF 1.7.1 with twoPhaseEulerFoam in OF 2.3.0? And then, I will be able to upgrade my costume solver (twoPhaseEulerFoam+population balance) to O.F 2.3.0 one?

However, my view is this fact that I could compare the costume solver with standard solver in O.F 1.7.1 and then, moving forward into O.F 2.3.0?

I would be appreciated if you let me know your comment.
