Default Face handling in Parallel UDF

Hi @all,

I'm currently busy with parallelizing my DEFINE_ON_DEMAND UDF.
What i want to do is to write out the nodal coordinates on a wall-surface.

It is working perfectly in serial and generally working in parallel, but unfortunately I get more nodes written out than in serial. I think that the identification of the PRINCIPAL_FACES (to determine whether a face belongs to a partition or not) doesn't work properly and that the UDF touches some faces more than once.

the most important part of the UDF:


and a part of the file with the wrong nodes:


Can anyone tell what might be the reason (and a possible solution )
