Dear Foamers,

I am using the library swak4foam for quite a while and I am really satisfied with it.
So far, I used it for evaluation of expressions which the solver produces, like pressure drop, velocity and so on.

Now I would like to know if it is possible to use a swak4foam function value which is defined in controlDict in the solver.
I found this document
http://openfoamwiki.net/images/e/e6/...oam_README.pdf

where is written that

swakSourceFields
These classes allow to manipulate the solution. To use these the solver has to be modified.
SwakSetValue
sets values according to a mask or the mechanism provided by basicSource
SwakExplicitSource
Uses the calculated source term on the right hand side of the equation
SwakImplicitSource
Uses a calculated scalar-field to add an implicit source term (source is without the actual field)

I am really interested in using an expression, not as implicit or explicit source term but as an expression during run-time which is updated in each iteration.

So my questions are:
1. Is it possible to define swak4foam-functions, i.e. in the controlDict, and to use them during run-time?
2. How can I use them? Do I need to modify the solver?
3. Is there an example somewhere?

I am happy if there is given an example somewhere and am able to reproduce and transfer the example to my case.

Thank you very much for an answer in advance.

Kind Regards
Anne

There are examples for the use of these classes in Examples/BasicSourceSubclasses. For solvers that support BasicSource no modification is necessary. Not sure how things are with 2.2 which has with fvOptions an improved version of BasicSource

Thank you very much for the answer, Bernhard.
It's been a while since I wrote the post above.
Finally I had a look at the examples of Examples/BasicSourceSubclasses.

I also installed a new swak-Version ( swak4Foam_2.x) using OpenFOAM-2.1.1

The installation was successful as the command

ls -l $FOAM_USER_LIBBIN

The problem is that I inadvertently "disabled" the basicSources while adapting them for 2.2. I pushed a fix to the development repository. If you don't want to download that go to your copy of the sources and in Libraries/swakSourceFields/swakExplicitSources.C add

#include "swak.H"

before the first #ifdef. Also do so for swakImplicitSources.C and swakSetSources.C
