Reply To: How to setup a stable sand layer by using Eulerian granular multiphase

[Mepal]

Many thanks Rob for your suggestion,

 

For the steady, I checked the convergence, mass flux, and hest flux. I think nothing strange. Below is their pictures.

Moreover, for the transient, I checked the convergence, mass flux, and hest flux. I still think nothing strange. Below is their pictures.

That is the reason I am still curious why iterating with steady, the height of granular decreases and vanishes (although no mass and heat loss!...the pictures above). But with transient, the granular layer is stable after many iterations.
