Trying to chase down an error and am wondering if anyone has run into this issue before. I am simulating a 3D cylindrical fluidized bed using twoPhaseEulerFoam (parallel run using 24 processors) and have received the following stack using both the Gidaspow and SyamlalOBrien drag models:

The run is terminated after 2sec for Syamlal, 4sec for Gidaspow. Any thoughts or guidance are much appreciated.
