DPM particle managing
 

Hello there
I'm studying water injection(900kg/s) into the hot&high speed jet(M=4, T=4000K, 600kg/s) with 2d axisymmetry.
For convience and ensuring convergence all URFs are set as 0.05. injection type is singe(from other post single injection was not recommended for high mass flow rate but..)
The problem is that there are number of particles (now it comes to 1.2 M ) and, therefore, too much time takes to calculate for just few millisec.
Is there any way to reduce calc time for this?
Thanks in advance ;)
