Hello together,

I am using the macro expansion functionality to dynamically set the names for my boundary patches. Now I implement a code stream on a boundary patch. To access the mesh data on the respective patch I use mesh.boundary.findPatchID("patchName"). And here I don't find a way to replace patchName with my marco expansion. It seems the parentheses are not compatible with the macro expansion.

Does anybody have an idea as how to solve this or could suggest a work-around?

patchNames.h

boundary_names
{
    OUTLET_NAME		outlet;
}

0/p

#inlcude "../patchNames.h"
$boundary_names.OUTLET_NAME
{

type 		fixedValue;
value 	 	#codeStream
{
... 
...
code
#{
... 
...
...
// this is where I want to use my macro expansion instead of writing "outlet" out:
const label id = mesh.boundary().findPatchID("outlet");
...
}#
}
}

It is probably late...

You can access a dictionary name by simply using the dictName member function

const word patchName = dict.dictName();
...
const label id = mesh.boundary().findPatchID(patchName);

If you take a look at the dictionary class, there are two member functions, name() and dictName()

...
        //- The dictionary name
        inline const fileName& name() const noexcept;

        //- The dictionary name for modification (use with caution).
        inline fileName& name() noexcept;

        //- The local dictionary name (final part of scoped name)
        inline word dictName() const;
...

The name() member function returns a so called "scoped name"

"/Volumes/SourceCode/projects/foam/3-weeks-training/week_3/day_11/1_bc_with_codeStream/codeStream_BC/2Delbow_UparabolicInlet/0/U.boundaryField.velocity-inlet-5"

But the dictName() returns the (sub)dictionary name...

"velocity-inlet-5"
