cinmar is on a distinguished road
Hi Guys,

I have the following problem. I should perform a DPM (uncoupled). My flow solution is unsteady. The flow time step is very small and the mesh size is very big (9 million).

What kind of particle tracking should I use for my particles?
I know that the most correct one is the unsteady one but the particle residence time is around 10-2 that for me means to run kind of 100000 iterations....computationally too much expensive (I should wait months). If I run a steady one I can use only the solution at that timestep. Can I use the mean flow field instead?

Thanks for you help,
