Hello All,

I am trying to create a setup case in sprayFoam, where I want to study liquid jet breakup using the Eulerian-Lagrangian method. Ideally, I want both fluids to be treated as an incompressible flow. There will be no reaction and combustion. But evaporation and phase change is allowed. Also Later on I want to do thin film modeling too.

Currently, the problem I am facing is strange. Here is the execution print that I am getting:

As it is not showing any error message I don't know what is going wrong in it. But it should have calculated the courant number before entering in a time loop.

I am attaching my case study please have a look into it. Any guide/help/suggestion will be deeply appreciated. I need to resolve this urgently.

could you find a solution for your problem?i have exactly the same problem with buoyantPimpleFoam. it just stopt withourt running
