Hi,

I'm running reactingFoam using a different geometry from the tutorial and GRI-Mech for the chemistry libraries.

I am able to run this in parallel, but when I try to run reconstructPar after the parallel run is over, I get this error after some time. I have output dumps every 0.001 seconds, and this goes fine until 0.007, and then at time 0.008, it fails.

I searched the forum for reconstructPar but did not find any post dealing with this. Please help.

Error below.

Thanks,

Kumar

Hi,

A bit more information on this. What seems to be happening is that some of the species files are missing. So, for instance in processor1/0.007, I see data for O, H2, CH4, CH3, C2H4, etc., but the file for O2 is empty, which is why the error arises.

My question is why is the file empty? The run shows no errors. So why are some of the species missing for some of the times? Is this a known bug?

Thanks very much,

Kumar
