Maximum parcel count exceeded

sarahtuvia · June 13, 2016, 12:22

Hi
Im running a case with a large number of particles and it stops with the message:

Unable to stamp 992424 new parcels. Maximum parcel count exceeded.

Whats the meenning of it and how can I get over it ?

Thanks

I believe there is a setting under Solvers > Lagrangian Multiphase that will allow you to change the max parcel count allowable.

The parcel count is simply the number of particles in a parcel and the limit is a computational safety valve of sorts. The Lagrangian solver can take a very long time in some cases and not having a limit can result in your solution dragging out much, much longer than you hoped for.

Thanks, but I can not find in solvers > Lagrangian Multiphase any limit of the particles number. Could you instruct me more specificly where can I find it ?

Perhaps I was mistaken. I do not see it either.

I have same error in DEM model, could you fix it?
