Greetings,
I am having some issues when using the collisionModel "pairCollision" combined with Adaptive Mesh Refinement (AMR) with the CollidingCloud/Parcel. I want to model particle-particle collisions and adhesion using the deterministic soft sphere model available in OpenFOAM, and AMR is mandatory for my framework (VOF-LPT). My solver works fine with AMR while using the CollidingCloud without a collisionModel, with "collisionModel none". However, when I use "collisionModel pairCollision", I get the following error: --> FOAM FATAL ERROR: Global positions are not available. Cloud::storeGlobalPositions has not been called. I tried running a simple case with DPMDyMFoam and icoUncoupledKinematicParcelDyMFoam, for the injection of particles in a box. The same problems occurs when using "collisionModel pairCollision". I have tested this in OF-v1812 and OF-v2112. I have attached the simple case files bellow, in case anybody wants to try it. Maybe my case setup is causing this issue? Has anybody experienced the same problem? P.S.: I am using the dynamicMesh solver "dynamicMultiDimRefineFvMesh" from the "TwoPhaseFlow" library in order to refine the velocity magnitude and velocity gradient fields. For my VOF-LPT simulations, I refine the alpha.water field. |
