euler-euler for wind blown sand flow
hi bros,

I adopt euler-euler model to simulate wind blown sand flow. The primary phase is wind flow and the second phase is sand. Air blow into the tunnel to get the sand particles "started", which are included in the case file.

Some questions are listed as follows

1 in the "cell zone conditions" tab, how to assign the two different phases? Could they be assigned different phase separately or only set as mixture?

2 in the "boundary conditions" tab, how to assign the two parts as different phases?

3 in the "boundary conditions" tab, which type of boundary condition fit for the interface of the "sand" and "air"?

Thank u guys~~

here is the case link. virus free
