How to add Exner equation in settlingFoam
 

Hi OpenFoamers,

I am doing some research with settlingFoam.
Now I want to add exner equation in settlingFoam to calculate the bed elevation.

Since exner equation is solved in a 2D bed mesh, but in settlingFoam 3D mesh is used, how to add the Exner equation in settlingFoam.

All my experience about revising OpenFoam is like the case "add temperature into icoFoam"

Could someone help me?

Best

anyone who can help? Thanks
