66 | ! Description: |
---|
67 | ! ------------ |
---|
68 | ! This routine combines data of the PALM-subdomains into one file. In PALM |
---|
69 | ! every processor element opens its own file and writes 2D- or 3D-binary-data |
---|
70 | ! into it (different files are opened for xy-, xz-, yz-cross-sections and |
---|
71 | ! 3D-data). For plotting or analyzing these PE-data have to be collected and |
---|
72 | ! to be put into single files, which is done by this routine. |
---|
73 | ! Output format is NetCDF. Additionally, a data are output in a binary format |
---|
74 | ! readable by ISO2D-software (cross-sections) and by AVS (3D-data). |
