[OpenFOAM 3.0.1] DPMFoam domain decomposition bug

Hi All,
I am currently experiencing a weird bug whereby my case is freezing after attempting to update the kinematic cloud, but only when decomposing my mesh in a certain way. My case study models a particulate flow down a pipe, with cyclic boundary conditions placed at the ends and the LES-WALE turbulence model. When running in serial there are no errors and the solution seems reasonable. However, when decomposing the mesh (scotch or simple) in the z-direction the output file freezes at 'evolving kinematic cloud'. When decomposing the mesh in the (r,theta) directions the solver works again, but this seems like a very inefficient way to parallelise my pipe, especially when I start splitting it into 64 processors. My case directory can be found on this dropbox link: https://www.dropbox.com/s/qz9wpb5wt7...PM.tar.gz?dl=0 and I have attached the output file below. I have changed the case file slightly so that it runs (with the same issues) on the standard DPMFoam solver rather than my altered one. If someone could take a look at this I would be very grateful! Thanks, Charlie |
