Reply To: CFD-DEM coupling to simulate liquid droplet deposition into the powder bed

[z.sang]

Thank you very much for your reply. :)

From you advice, it seems the mesh refinement is really important. Actually, because I am running two-way fluent coupling simulation which requires mesh size larger than particle size, I set the mesh size to 20 µm. For the current feasibility study, I have to consider the efficiency. However, in future I would definitely consider the mesh refinement.

Fow now, it is more likely that droplet smashed into the powder bed instead of flowing into the powder bed due to the capillary force. I am really confused.
