it seems to work but I'm not 100% sure about the results...

If I understand you correctly, you want to do a plain average of the fields over the existing time snapshots?

In addition, do you mean that the average results for a dynamic mesh are acceptable for doing

I experienced a problem when using the post-processing utility R to evaluate the Reynolds stress tensor based on a compressible simulation using a kEpsilon turbulence model. The Reynolds stress tensor is needed as initialization for a RSM simulation.
The problem I experienced is basically related to the compressible nature of my simulation and it seems that the R-utility is written exclusively for

I am facing a problem of mapFields taking too long to map fields from a fine mesh to a coarser mesh. I am running simulation using sprayFoam, and want to coarse the mesh to achieve faster solution. So I executed:

in the aacheBomb-coarse directory and it is running without errors. However, it gets

However, I would like to view the average over say the last 100 steps, to view the statistics of the solution. Is there a way I can do this in paraFoam?

Also, how is convergence judged in this example? Normally I judge conversion in a
