I have written this SWAK function to write the expression at each outputTime(not each timeStep):

n1_totalTemperature
    {
        type swakExpression;
        valueType surface;
        surfaceName normalPlane_T0_1;
        verbose true;
        surface {
            type plane;
            basePoint       (0.01725 0.002 0);
            normalVector    (1 0 0);
            interpolate true;
        }
        expression "sum((T+0.000497517*magSqr(U))*rho*area())/sum(rho*area())";
        accumulations (
            average
        );
        outputControl outputTime;//outputTime;//
        outputInterval 1; // 5000
    }

bu it writes still the values in each time step:

why?

[wyldckat]

Hi Ehsan,

In this case, swak4Foam doesn't use "outputControl". It only uses "outputInterval". Which means that it you'll have to use something like this:

outputInterval 10;

Best regards,
Bruno

[immortality]

Hi Bruno
1)what do you mean by "in this case"?
2)I have a variable timeStep.there isn't any other way to have outputs concurrent with folder writing times to save time?
I saw this,what does cloud mean?

createThrePointSet
    {
        type createSampledSet;
        outputControl timeStep;
        outputInterval 1;
        setName threePoints;
        set {
            type cloud;
            axis x;
            points (
                (0.1 0.14 0.0001)
                (0.0 0.02 0.0001)
                (-0.1 0.02 0.0001)
            );
        }
        writeSetOnConstruction true;
        autoWriteSet true;
        setFormat vtk;
    }

3)can use phi on patch in sampledSurfaces?
thanks.

[wyldckat]

Hi Ehsan,

1) From what I can figure out, swak4Foam can use "outputControl" in some other function objects. But in this case, namely for "swakExpression", this doesn't work.

2)

I have a variable timeStep.there isn't any other way to have outputs concurrent with folder writing times to save time?

It's necessary to change the source code of swak4Foam for this to be possible.

I saw this,what does cloud mean?

I'm not familiar with this function object... but "cloud" is used for indicating multiple points for sampling.

3) As I said on the email a few minutes ago, "phi" cannot be used with the "sampledSurface" in OpenFOAM's function object, which is why "faceZone" has to be used instead.

Best regards,
Bruno

For historical reasons all function objects in swak that are based on the simpleFunctionObjects are not based on OutputFilterFunctionObject and therefor do not support outputControl (other function objects do). Incidentally my current development version already supports this.

Also writing at fixed time intervals is already supported

Hi Bernhard
when does the new version will release?(current version i use is 0.2.3 is there a newer one?)

When it is ready. Intermediate versions are found in the mercurial-repository. But they may contain bugs so use with care. New features are documented in the README

No. That is the latest released one

[manju819]

Hi Bernhard
I'm writing the variable on the patch using swakEpression

 Ttop {
                type    swakExpression;
                valueType       patch;
                patchName       top;
                outputControlMode timeStep;
                outputInterval  100;
                region          stratumCorneum;
                expression      "T";
                accumulations   (
                        average
                );
                verbose         true;
                autoInterpolate true;
        }

I added libraries also but it is showing the error

Quick answer: Edit the "system/controlDict" and add the library "libsimpleFunctionObjects.so" in "libs" before "libsimpleSwakFunctionObjects.so", e.g.:

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

[afshinb]

I'm using OF 3.0.1 and just installed swak4Foam 0.4.0 from here.
installation process seemed to went well. but now I'm getting this error.

is it about the libraries location?
where should swak4Foam libraries be placed now?

Quick requests:

1. Please provide the "system/controlDict" file you're using in your case.
2. Please provide the complete output from the solver.
3. Please provide what the following command gives you:

Greetings Afshin,

Please keep in mind that OpenFOAM is very picky with every single detail Any missing detail can be the reason for it to not work as intended.

For this list, I hope the missing closing bracket is not missing from your complete "system/controlDict" file. In addition, I hope you only have a single "libs" entry. Beyond that, I don't see any specific problem.

Remember what you posted in your previous post, namely post #10? Namely this:

This is only a very small part of the output that the solver gave you on-screen. I need the complete output, so that I can confirm if there were any other diagnostics that OpenFOAM gave earlier or later.

are you looking for this directory?

/opt/openfoam30/platforms/linux64GccDPInt32Opt/lib

If you didn't change anything from the conventional installation instructions for swak4Foam, then I was looking for the correct directory. And it doesn't exist, then that probably means that swak4Foam did not build at all

If this diagnosis is correct, then I need the log file "log.make" that results from this command:

./Allwmake > log.make 2>&1

You can compress the file with this command:

gzip < log.make > log.make.gz

Then please attach the file "log.make.gz" to your next post.

Best regards,
Bruno

yes you are right, there was a missing closing bracket but fixing it didn't solve the problem.
is there a problem in having multiple libs entries ?

that's the complete output:

thank you for your kind responses.

Quick answer: The log file told us the whole story!
The problem is that you built swak4Foam with root powers (probably using sudo), because it tells us that one of the installation folders was this:

/home/afshin/OpenFOAM/root-3.0.1/platforms/linux64GccDPInt32Opt/lib/

"root-3.0.1" is not "afshin-3.0.1", which is why the libraries are not being found.

OK, let's see if I don't make a mistake in the following code... please carefully run these commands:

cd ~/OpenFOAM
mkdir afshin-3.0.1
sudo mv root-3.0.1/* afshin-3.0.1/
sudo chown -R afshin:afshin afshin-3.0.1

And finally, check if the folder I asked about in a previous post exists as intended with the desired libraries:

ls -l $FOAM_USER_LIBBIN

If all went well, it should list the libraries we want, such as "libgroovyBC.so".

For example, having the following two lines in "system/controlDict" is wrong:

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

It's wrong, because OpenFOAM will only read the first one. Therefore, the correct way is something this:

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

Quick answer: "alpha.water" problem... that has to do with a problem that swak4Foam has with field names that have dots in their names. Googling... results:

Hi,


I would like the output time step of swakExpression be written in 7 precisions. My current command is as following:

    interfaceTemp
    {
    ignore_unimplemented_simpleFunctionObject::updateMesh true;
        aliases {
        alpha1 alpha.water;
        }
    type swakExpression;
    valueType surface;
    surfaceName interface1;
    surface {
        type isoSurface;
        isoField alpha.water;
        isoValue 0.9;
        interpolate true;
                writePrecision 7;
    }
    verbose true;
    expression "T";
    accumulations (
        average
        min
        max
    );
        outputInterval 20;
        timePrecision 7;
    }

But it is still written in 4, although the processing time step precision is 7:



# Time average min max
31.8321 343.078 342.996 362.95
31.8321 343.065 341.481 362.862
31.8321 343.061 342.085 362.834




I will apprciate any help.


Cheers,


Elham

AFAIK (but I'd have to check the sources to be sure) swak makes no effort to change the write precision. So unless the underlying Foam-implementation doesn't support this on a functionObject-level (I'm not aware of this) your best chance is to set it in the controlDict for the whole run (everything will be written with 7 digits)

Ok. Thanks for your comment.
