lagrangian model in cfx
 

hello.
I have been simulated a 2D tube (L=.2 m and R=.002 m).
Nanofluid (water and TiO2 (D=21 nm), continues and particle transport solid).
result are good but I have a question.
If we change the number of particles at inlet, have we various result?
when I increase number of particles, every iterate need long time for converging!!!
Can I do this simulation with more than 10,000,000 particles at inlet by usual laptop (2 core)?
for example 4 mg Fe3O4 at inlet is about 1E17 particle...
Thanks
