An inquiry about set_flags.f

MFiX How to
#1

Dear Developer,

I am trying to implement particles cycling in the y-direction while the gas is not cycling. Dr. Jeff. gave me some valuable advice: use cyclic-BC and modify the code set_flags.f. I followed the advice and it works fine in serial mode, but in DMP parallel mode (i.e., NODESJ>1), set_flags.f doesn’t work resulting in both the gas and the particles are looped in the y-direction. I tried changing ‘J == JMAX2’ to ‘J == JMAX3’ and it still doesn’t do anything. Can you tell me why this is and which codes should be changed in DMP parallel mode?
Thanks for your help!

I’m not sure what the issue is. It seems that the modified FLAGS_N is not getting properly distributed to all DMP nodes (using send_recv or scatter/gather)

OK, thanks！It doesn’t look like it’s going to be resolved for a while.
