Hi all,
I have had to partition my flow model into segments due to element limitations and I am testing whether I can conduct my analysis by partitioning my model into smaller models and preforming the same analysis by carrying the solution data of one part into the inlet of the succeeding part.
I have attempted to export and import the data in a .dat file format but Fluent could not carry the information forward into a succeeding simulation.
It could read the data but said the "data size does not match current grid".
Warning: read-data: data size does not match current grid.
Warning: case and data files are inconsistent; zone 2, case [1,343], data [1,1029]
Warning: case and data files are inconsistent; zone 1, case [1,882], data [1,2744]
Warning: case and data files are inconsistent; zone 5, case [883,931], data [2745,2842]
Warning: case and data files are inconsistent; zone 6, case [932,980], data [2843,2891]
Warning: case and data files are inconsistent; zone 7, case [981,1176], data [2892,3430]
............. etc.
The topology of the outlet of the first segmented model and the inlet of the second model are simple 10 cm squares with the same number of elements.
Does anyone have insight into how to overcome this issue?
Please see attached JPEGs of my simplified test analysis.
Best Regards and Many Thanks.
Hello Mr. Ryan. The '.dat' file is used to write the data value for the present mesh conditions. If you run a case and saved the data value as '.dat', it will store the data value of each every mesh element in the case. If you import a different mesh and try to read the data value from '.dat', it will show error as the mesh are different. From my understanding what you need is the data values from 'outlet' of the first mesh and need to give it as the 'inlet' of the second mesh. For that I recommend to use the 'file>>write>> profile' of the outlet in first case and 'file>>read>>profile' in the second case and give the inlet parameter as the read profile for the second case. Can look into https://www.afs.enea.it/project/neptunius/docs/fluent/html/ug/node266.htm , for some insight.
