Hi Foamers,
I am getting an error while trying to reconstruct a openFoam case which I ran.

Case description:
Its mixer vessel case with sliding mesh approach for agitator. The simulation ran fine and completed. Now When I am trying to reconstruct this this case using "reconstructPar" I am getting following error.

It is strange because it never happend earlier. I tried suggestion from other threads related to reconstructPar such as using the script to construct the mesh first then fields, using higher RAM but the error seems to be related to fvPatch fields.

Please can anyone help me with this?

Hello Asif

I can't say what causes the problems reconstructing your fields, but maybe you can try to visualize your results in decomposed mode. You can open the results in Paraview and select the decomposed case (instead of reconstructed, which is default when you open Paraview) in the property section.

Hi Atul,

Yeah, it works in decompose level in Paraview but does not provide the information about bubbles. So, generally I reconstruct the case then convert the foamToVTK data which contain the information about bubbles. That's were I am facing the problem.

Do you know how to convert the the data from n processor directly to VTK format.

The syntax I am trying is not working.

'mpirun -np 32 foamToVTK -parallel'

Hi Asif

Maybe you can go to each processor and run foamToVTK on desired fields/sets, etc. Alternatively, you can write a script that runs over all the processors. I haven't worked with Bubbles, so I can't help much.

Hi Atul,

Actually its not working, but thanks for the help. I will try to look into the source code for this.

Thanks and Regards
