CGNS error reported from FLUENT export in parallel processing
Hi,
When I try to export cgns file format from (in acoustic mode), the paralel processing result and serial result differs from each other. CGNS files which of them are exported from PARALEL processing in fluent cant be read in softwares. But serial results are working. Is there any idea? Thanks |
The parallel and serial results will be different. In parallel, it will export data from each partition separately.
I recommend to switch to serial mode and then export data. Otherwise, you will have to parse through the data file and merge the data back together again. You just need to realize that Fluent is exporting the data in blocks (each node exports it's own data and writes/appends it to the data file separately). How easy it is to implement this fix depends on what tool you're actually using to read the data files. |

CGNS data files exported from parallel fluent contain values of zero. All fluid variables behave like this. Did you ever encounter this problem?
