Dsmc Ccontrolling the no of particles that is simulated
 
Hi everyone ,

I am trying to understand the dsmcfoam to simulate high knudsen no flows .

I want to simulate 330053 molecules in my flow .

I took N2 as the gas thats being simulated .

I have no idea of what is " no of equivalent particles " and this total no of molecules means .

Is there anything over internet that would help me in understanding the difference between the two ?

thanks
sud

Have you find any information related to the problem?

Apparently nEquivalentParticles is the number of real particles...

At the moment I don't have any idea how to determine properly this number according to simulation case, cell number etc...??????

Anyone having idea related to this?
