Animating unsteady data from Fluent in Paraview..

Hello,
I would like to create an animation from an unsteady calculation done with Fluent14. Of course I could do it directly in Fluent, but I'd like to do it with Paraview. I have already done postprocessing in Paraview from Fluent files, but only for steady calculations, that require only to load one Ensight file exported from Fluent's calculation. Now the question is : is it possible to do -in Paraview- unsteady animations from Fluent file(s) ? I never used OpenFOAM, but I know it allows Paraview to somehow load all the time steps in one file, and then create an unsteady animation in Paraview.. Is that possible from Fluent too ? If yes, how ? Should I export several time steps from fluent and export for each one of these an Ensight file.. ? But that would be very time consuming! Or is it a way to load only one file exported from Fluent and have all the temporal information contained in it ? Thanks a lot, Arnaud. PS : I'm using Paraview 3.12 |

Hi all!
I made a small python script, that post-processes FLUENT unsteady results: Code:
#!/usr/bin/python # Load system libs import os, glob # Load paraview staff from paraview.simple import * # Some magic to make paraview not reset my zooming settings servermanager.LoadState("qq.pvsm") SetActiveView(GetRenderView()) Render() Render() # Loop through dat files for file in glob.glob(os.path.join('./res/', '*[05]0.dat') ): # Unlink old dat file and link the new one os.unlink('fluent.dat') os.symlink(file, 'fluent.dat') # Delete old state object from the pipeline browser Delete(FindSource('fluent.cas')) # Reload state servermanager.LoadState("qq.pvsm") # Check which file we are rendering print file # Do rendering SetActiveView(GetRenderView()) Render() WriteImage(file+".png") I tried the batch mode, but it resets all my coloring settings as well as my zooming preferences. Moreover it renders the frame around color scale. Hint: qq is a State file, where you save you scene settings.

Thank you Alex !
I tried to use your script, but I always get an error message (syntax error) and cannot find the solution (I am not really good at python). Are you loading *.dat-files and the corresponding *.cas-file? Lilly |

Dear Lilly!
We can try your files. So please upload archive with your example FLUENT files and I will see what's wrong and give here some small tutorial with your data and my modified script.

How to read Fluent Ensight result files in ParaView:
Copy and rename your .encas file to "something.case" Open this file using ParaView and voila! Please write back if you have any problems |
