dsmcFOAM output

Hello ppl,

I solved a simple problem using dsmcFOAM solver. Now i need to extract the data out of it. I used the dsmcFieldsCalc to obtain the Pressure temperature and velocities. Now There was a folder named /Post processing

Within the post processing folder, i find a forces.dat file.

What is this file?

I dont understand anything from this file. Can I use that dat file to plot in matlab ??

Help me guys

Thanks

Results can be obtained by running dsmcFieldCalc "OR" adding force functions in the controlDict file (as in wedge15Ma5 tutorial).
The macroscopic(temp/overallT, P,Umean etc.) results are ensemble averaged output.
You can edit controlDict force function with with "resetOnOutput off;" for time averaging from initial time (0) "OR"
set "resetOnOutput on;" to get for time averaging from a later time ( after a getting steady result).
