46	! Description:
47	! ------------
48	! This routine combines data of the PALM-subdomains into one file. In PALM
49	! every processor element opens its own file and writes 2D- or 3D-binary-data
50	! into it (different files are opened for xy-, xz-, yz-cross-sections and
51	! 3D-data). For plotting or analyzing these PE-data have to be collected and
52	! to be put into single files, which is done by this routine.
53	! Output format is NetCDF. Additionally, a data are output in a binary format
54	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
