Hi Foamers!
I need some help with a propeller simulation (transient). As a quick note, I'm quite new to OpenFoam. A brief description of the project: I created the propeller geometry with Solidworks and then created the enclosure and the mesh with Salome. There are two regions: the main enclosure (that doesn't rotate) which represents the freestream flow and the propeller enclosure (which should rotate) that contains the propeller. The meshes of both domains are created separately and then merged using mergeMeshes. The rotor cellZone region is then set using setSet. I also use topoSetDict to add all AMI faces to a faceSet. Finally, due to the size of the simulation, I run it in parallel using 20 procs (using the singleProcessorFaceSets to keep all AMI faces on the same processor). The simulation blows after a few iterations. I must note that the simulation blows when it's run in series too. I've checked the mesh and it's okay (see attached log file). This is the log of a failed parallel simulation. Code:

It's actually a slip wall condition). I'm aware that this names are confusing and I'll fix it now. This is the link to the project files (I deleted /constant/faces to reduce it's size). https://drive.google.com/drive/folde...bE?usp=sharing Any help would be appreciated! |
