Hello Rob

 

I don’t have info of the flow field, I’m gonna run the case again and monitor the flow field just before the divergence and I’ll tell you.

 

Regarding the scale particle density, I think I understand you, correct me if I am wrong. What you mean is that the dynamics of the free falling particle is governed by the difference in the densities of the body and the carrier fluid, This is clear to me, now you tell me that I can scale the densities maintaining the difference between both, in order to avoid divergence when I define smaller values of the mass, this without scale the fluid domain. Imma try it.

 

…..Another point of interest in my analysis is to compare numerical soltion with an analytical solution of the Basset–Boussinesq–Oseen equation.

 

Rob, I would like to know if in this same thread, you could give me some suggestion to stop the calculation when the particle reaches the bottom of the domain.
