Hello,

I'm using funkySetFieldDict to define the velocity of my internal field. Unfortunately after using the funkySetField command all the other boundary conditions defined in the U-file are replaced by zeroGradient. Is there a way that funkySetField keeps the previous defined velocity boundary conditions? Otherwise it is quite time consuming to correct every single case.

See my used funkySetFieldDict:

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

expressions
(
    internalfield
    {
        field U;
        expression "(18*((log(pos().z/0.0002))/(log(17/0.0002))))*vector(-0.966,0.259,0)";
        }
);

Thanks for any help in advance!!!
Regards
Nils

The solution exists since the first versions of funkySetFields and it is even documented at http://openfoamwiki.net/index.php/Co...and_line_usage : keepPatches (documentation is a fascinating thing ...)
