The file in attachment should help, as it's the patch provided in the bug report. To apply it, do the following steps:

1. Download the attached file "writeFieldsGeneralFunctionObject.C.patch".
2. In the terminal, go to the folder where you have the swak4Foam source code and run the following command:
   

   patch -p1 < ~/Downloads/writeFieldsGeneralFunctionObject.C.patch

   Where I'm assuming you downloaded the file into the folder "~/Downloads/", so change it to your need
3. Now you can run "Allwmake" once again, as you did before.

Best regards,
Bruno

Hi Bruno,

I have same problem with installing SWAK 0.4.0 on OF-2.3.1. First i installed the SWAK and didn't noticed the error in end of the log file i attached here.

If you have your own function-plugins you can specify them using the SWAK_USER_PLUGINS environment variable and they would be compiled now. If you don't know what this means: don't bother. You propably don't need it

If you want to use swakCoded-function object or compile software based on swak set the environment variable SWAK4FOAM_SRC to /home/behzad/OpenFOAM/behzad-2.3.1/swak4Foam/Libraries (most people will be fine without setting that variable)

When i tried to run decomposePar i got warnings attached:

Although your patch was for previous version, i applied it and nothing changed.

Thanks in advance,

Hi dear forumers,

I want to calculate falling droplet velocity using swak expresions. but when I want to decompose the domain or execute the solver i get error.
my bison version is:

bison (GNU Bison) 2.7.12-4996

my swak version is 0.4.0. I use OF-2.3.1.
My controlDict added codes for swak:

I attached swak make log and solver execution error below.

any comment is appreciated,

[behzad-cfd]

According to attached Error.txt file, the shared object libtwoPhaseInterfaceProperties.so isn't exist in openFoam library any more. maybe there was in older versions, now i have two questions:

1- Do i need libtwoPhaseInterfaceProperties.so for creating and tracking droplet interface or only libinterfaceProperties.so will suffice?
2- If i need libtwoPhaseInterfaceProperties.so, can i add this to openFoam library? and how?

Any comment is appreciated,
Kind regards,

[behzad-cfd]

No one have an idea?

Greetings Behzad,

I've finally managed to take a quick look into this and I have to say that I'm a bit confused, mostly because I'm not familiar with the reason why you're loading all of those libraries in the "libs" list within "controlDict".

As for the log file from the installation, only fieldReport didn't build, so this shouldn't affect your case.

Therefore, to address the problem, I suggest that you change the "libs" entry to this:

libs (
    "libsimpleSwakFunctionObjects.so"
    "libswakFunctionObjects.so"
);

I suggest this because I don't see any reason why you need to load any other libraries than the ones that swak4Foam needs for the function objects to work as intended.

Of course this also means that you must only use these with the correct multiphase solver and do not try to use these function objects with an application such as execFlowFunctionObjects.

Best regards,
Bruno
