CGNS from bak-File
Hey there,
I'm trying to figure out a way of exporting .bak-file data into a cgns file. Problem is as follows: when .bak-files are written with the "selected variables"-option, the command to export to cgns fails with "file has invalid topology" which I think means, that the mesh is missing and therfore it cant be exported. However, I am able to access the results, when loading the final .res-File in Post and adding the baks as timesteps. Is there any way to tell Post to just export that into a CGNS? The same thing works just fine for transient results. There I can specify the final .res-File and extract data for each timestep with the "-timestep" flag. https://www.sharcnet.ca/Software/Ans.../i1306563.html |
Why do you write a backup file without mesh? In my opinion, a backup file is to be able to recover from a crash. In that sense a backup file without mesh is quite useless. Or do I overlook a situation where it is useful?
Nevertheless, maybe you can try to interpolate the .bak-file on the original definition file (Not sure if the interpolation works with a bak file without mesh. Maybe the interpolator can use the x,y,z coordinates, or node numbers, if available in your bakfile). Do the following: - Open the CFX-launcher - Open the Command line - Type: cfx5interp -res file.bak -def file.def - If it works, you obtain a def file with the backup results as initial guess. Maybe you can export this to cgns? - Alternatively run it with the solver manager for 1 iteration. Maybe solve only turbulence, (use expert parameter solve fluids=f, solve energy=f to not screw up your existing solution too much) - Export results file to cgns Use cfx5interp -h for help Hope this helps. |
