Please Reply,
I am doing analysis of flow over the wagon. First i need to do the mesh convergence. My output parameter is the particle concentration over the wagon because i set the dpm on inlet. But when i am refining mesh to get the convergence i am struggling with the mesh convergence because more particles to come from the inlet. SO what should I do to get the convergence in the model. Should I choose the different output parameter in the parameter like drag force or something? Please help me out with it.
