Hi All,

I am working on two dimensional ash deposition model. In my project I use DPM method with Define_DPM_Erosion UDF, to simulate rebound or accretion of the particle. In next step I want to create deposition on the wall with Dynamic Mesh and Define_Grid_Motion. I am wondering how to manage this two UDF's.

In Erosion UDF we have this macro:

 F_STORAGE_R(f,t,SV_DPMS_ACCRETION) += Mdot / area;

I supose that macro is responsible for storage data of particles accrete on the wall.
My question is. Can I use F_STORAGE_R in UDF Grid Motion to simulate growth of ash particle deposition? How to set up proper motion of the cell node?

I will be gratful for any sugestions.

Hi,have you solved this problem? I am doing the same thing but I do not have a clue.
