Hi
Probably a rather simple problem, but I still need some help. I have OpenFOAM 1.5. I downloaded funkySetFields which worked alright, but when I type the command "funkySetFields" just to see if it works I get: command not found.
Why's that?
I downloaded the directory into the /utilities/preProcessing directory. Do I have to put it somewhere else or is there just a step missing?
Cheers, Sara

Hi Sara

Just a small question before we go into details :

Did you compile it :-)

Kind Regards

Ehm, nope, I didn't. Because I didn't know I have to. As a matter of fact I also don't know how to do it.. could you please tell me?
Thanks so much, Sara

[sara]

Ok
I got it. Thanks ;)

Hi
Now funkySetFields is compiled and should be ok. However I still have some problems. I tried to run funkySetFields. I wanted to set gamma to 1 in a certain area on the inlet of my geometry. I'm using interFoam. I think I did everything as explained in the wiki. But apparently something is wrong because I get these error messages:
schairer@schairer-desktop:~/OpenFOAM/schairer-.5/run_execute/geometrieI_interFoam_tests1$ funkySetFields . geometrieI_interFoam_tests1 -time 0 -field gamma -expression 1 -condition "pos().x = 0 && pos().y >= 0.049 && pos().y <=>= 0.049 && pos().z <= 0.051"

Hope someone can help me figure this out.

Hi Sara

Good Morning

You are using OpenFOAM 1.5.
It does not require to specify <root> <case>

Try your expression like this :

funkySetFields -time 0 -field gamma -expression 1 -condition "pos().x = 0 && pos().y >= 0.049 && pos().y <=>= 0.049 && pos().z <= 0.051"

and it shall work.

Hope that works else write back

Kind Regards
Jaswi

Hello Sara,

I'm facing the same problem: command not found.

How did you compile it?

Thanks,
Sagun

Compilation is described on the Wiki-page (depends on the version you're using - standalone or swak. But in both cases the process consists of one command)

Hello,

I'm using OpenFoam version 2.1.1 on Linux 11.10. and so I installed swak4Foam instead of the traditional funkySetFields. Unfortunately, I don't seem to be able to find the compilation step on the page http://openfoamwiki.net/index.php/Contrib/swak4Foam

Maybe its something very obvious and I'm missing it on account of my very limited knowledge of OpenFOAM and Linux.

Another general question: What is meant by the directory of sources?

I have swak4Foam installed in my opt/openfoam2011/src directory. Is that what the author is referring to?

Thanks,
Sagun

How about point 2: Building (http://openfoamwiki.net/index.php/Co...4Foam#Building)

The director you downloaded. In your case probably opt/openfoam2011/src/swak4Foam

Thank you so much for your help but I'm still getting the same error: command not found.

I'm trying to implement funkySetFields using a funkysetFieldsDict file in the system folder.

Here is how the file looks like:

FoamFile
{
version 2.0;
format ascii;
class dictionary;
object funkySetFieldsDict;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

expressions
(
InitialProfileVelocity
{
field U;
variables "u_f=0.949;z0=0.1;K=0.41;zground=184.557;";
expression "vector(0,1,0)*(u_f/K)*log((pos().z-zground+z0)/z0)";
keepPatches 1; //keep the boundary conditions that were set before
}
);

Is there something wrong with the approach I have adopted to implement funkySetFields?

Regards,
Sagun
