dsmcFoam : writing options : How to keep only field data ? Not Lagrangian
 
Hi !

I am running dsmc simulation of a gas flow with dsmcFoam, and I would like to be able to have a better control over the outputs of the simulations.

I want to write the macroscopic fields, and averaged fields at each writeTime
(RhoN, RhoNMean, UMean, ...) and keep them for post-processing.
BUT I do not need all the data included in the lagrangian folder (the properties of each simulated particle, 90% of the memory storage :eek:) I just need this data for the last time step to be able to continue the simulation.

The purgeWrite option does not suit me, as it erases ALL the data (macroscopic + lagrangian)

Is there a way to do what I want ?
Thanks for your help !

in Allrun.C,you can find the code

Thanks, I see the following line in the Allrun file for some dsmc tutorials:
Code:


runApplication reconstructPar -noLagrangian

But it only applies to the reconstructPar utility. I would like to erase the lagrangian folders "on the go".
