Hi,

I want to define my own function file and I have read up on how it is done. I do have some basic problems though that I hope to get help with.

I am using pimpleFoam as solver and as I've understood I need to copy the whole source code for that solver to my $FOAM_USER_APPBIN directory, rename it, e.g. modifiedPimpleFoam, and then create my function (userFunc.C and userFunc.H files). So far so good?

My first problem is that I can't seam to locate my $FOAM_USER_APPBIN directory. OpenFOAM is not installed under my /home but under /apps/OpenFOAM-6...
When I type ls $FOAM_APPBIN all is good but when I type ls $FOAM_USER_APPBIN I don't find the folder, since it is trying to access /home/<user>/OpenFOAM/<user>

Can someone please help me out here?

/David

You may used coded class instead, which resembles more closely the concept of an UDF. Some versions of openFOAM have them, and behaviour is different on the different forks:

here is the source code for said function object:
