Hello everyone,


I am working with multiphaseEulerFoam on a simplified case of droplet deposition on a surface. On a static mesh everything works fine.

If I try to activate the AMR, I get a couple of time steps where the refinement works fine and then the solver crashes.

Hi,

Did you solve this issue, I am also having a similar problem with AMR technique.
Could you please share with me your solution?

Thanks

I faced a similar issue with my bubble growth simulation. Playing around with the unrefinelevel helped get past the initial hurdle. I'm however still facing the issue at a much later time step. I still haven't been able to completely resolve the issue. Please do leave a comment if you find a fix.

Hello Venky_94,

I also tried playing with an unrefined level and my simulation crashed after few time-steps. I was wondering, did you get passed this step?

Please try this and see what happens; otherwise, share your fvsolutionDict and controlDict files.
