Yeah ! It works. Thank you, and I hope this version will be implemented in the next release of OpenFOAM, it's really a great work !

Best regards,

Peter

It is already working for you, but for your future reference: I have updated the library with updated instructions.
I could not maintain binary compatibility, hence it is mandatory to recompile your solver. Luckily, this can be done without making any changes to the solver.
I have written a script that can automatically recompile any solver for you, which is located in the "recompileSolvers" directory. See the updated README for instructions.

Is there an OF-5.0 version available?

It was implemented using OF's run-time selection mechanism and a dynamic library trick, such that it should work with any solver (that uses OF's libinterfaceProperties.so: inter(DyM)Foam, compressibleInter(DyM)Foam, multiphaseInter(DyM)Foam, interPhaseChange(DyM)Foam and very likely some more.)
[Disclaimer: I have only tried inter(DyM)Foam in my work.]

See the README.md on GitHub:

I did not yet know OF-5.0 was released.

I have just adapted the code to work with OF-5.0 for you (and others) and pushed it to the same GitHub page. Make sure to checkout the branch "of50", as is now also mentioned in the updated README file.

Hi Kevin,

May I get your advice on how to adapt old version Openfoam codes to newest version? I know it's not easy. But any general instructions are very helpful.

Put two similar codes from both the old and new version next to each other.
For example, if you have a custom solver based on interFoam in 2.1.x, then I'd open the real interFoam of 2.1.x and the interFoam of the new version.
Then by first comparing Make/options and then each individual source file of those two interFoams, I can figure out how to adapt my code to the new version.

Thanks Kevin for these wonderful advices! I will try out.

Hi Kevin, after I removed this library, Openfoam still asked me to set curvatureModel when using interFoam, how to avoid this problem?

What exactly did you do to remove it?
If OF is asking you to set "curvatureModel", the library is not removed.
You should remove the .so file from the directory $FOAM_USER_LIBBIN.

Hey Kevin
i saw your discussions on VOF smoothing and i see you 've been working on boiling flows.
i am also working on boiling and i am using intercondensatingevaporatingfoam solver
from OPENFOAM-V1612+ from ESI
I hve added dynamic meshing to it
it's however plagued with spurious currents.
can you please add vof smoothing for openfoam-v1612+ ?? add support for OPENFOAM ESI
my intercondensatinngevaporatingfoam is attached in this forum...
i'll send you the link if you want to try...

Dear all,
I m also validating two phase slug flow in T junction microreactor using interFoam with constantContactAngle of 140 and so on.......till now results matches nicely till slug breaking mechanism....but after that as slug move in main channel it start accelerating and its size increases till outlet comes......what is the issue,I am stuck now (by observation as one phase block other phase at junction and then it break slug, the slug in main channel accelerates)

I think someone can understand my issue....

Hi Kevin,

for some reason I cannot run ./Allget. At first there was an error saying wrong directory. I have figured that my sh was in bin/sh rather than usr/bin/sh.
Now when I run it I get error from line 33 that "(" is unexpected and pretty much all the other brackets in line 33 and 34. I am pretty sure they should be there and even after removing them I get a syntax error that line 42 "(" is unexpected (expecting "done"). This is seriously doing my head in...

I can ensure you that the script works for me, so especially the brackets should be correct.
First try executing the script by explicitly specifying the running environment (from the directory that contains the script):
Code:
sh ./Allget
If that doesn't work, what version of sh do you have?
Code:
sh --version
The script was written to work with bash. If you have a different shell (like kcsh), then the script has never been checked whether it is compatible. Try executing it explicitly using bash (if your machine has it):
Code:
bash ./Allget
As alternative: you don't need the script to use my library. It is just a convenience thing. In the README on GitHub I also wrote instruction to install my library without the Allget script.
In fact, all that Allget does is use your "list_of_solvers" file to repetitively call the getSolverMake.sh script for all solvers you wish to recompile. You can do that by hand as well (see the README on GitHub).
Then, getSolverMake.sh (I hope that one works for you) modifies some files of the solver like Make/files and Make/options to automagically link it against my library, and set its compilation location to $FOAM_USER_APPBIN: the place where custom solvers should go.

Hope that helps you.

Hey Kevin and Michal,

first of thanks a lot for the port and your detailed description on github Kevin!
I ran into the same problem that Michal had and managed to fix it, simply by replacing the first line:

#! /usr/bin/sh

with:

#!/bin/bash

in the Allget, Allwmake and the getSolverMake.sh script.

I hope this is helpful for other foamers out there.

Best regards,
Leon

Thank you for putting that out here.
In the meantime I'd run into the same problem with a student of mine who wanted to use his own laptop as well, for which we used that same solution.

I just wonder what the "proper" Linux way of writing the shebang is... Perhaps using env?
Code:
/usr/bin/env bash
