Particle tracking problem
 

I am simulation a Particle tracking model, using LES.

I use a steady state results as initial conditions to the transient mode.

In steady state the particle diagnostics gives,

|Particle 5um | Entered domain : 2000 |
| | Left domain : 18 |
| | Exceeded time limit : 1981 |
| | Integration error : 1 |
+--------------------------------------------------------------------+
| Particle 2um | Entered domain : 1000 |
| | Left domain : 62 |
| | Exceeded time limit : 924 |
| | Exceeded distance limit : 14 |

I have increased,

Max. particle tracking time = 20S
Max. tracking distance = 100m
Max. No. of integration steps = 1500000

Do I want to increase these limits again? (I have done many trials and this is the last trial conditions).

Or will there be any problem if I increase the "Max. particle tracking time" only as many particles in this fate?

I have done a similar simulation before without these errors. Only difference was no. of particles were 10 times lesser than this one.

I am glad to have your advises.
