Hi Foamers,
As you know, in gas-solid flows there are two time steps; one for continuous phase and the other for disperse phase which is usually less than first one. It is introduced as nSubCycles in openFoam. when running dpmFoam we see in terminal: Code:
Courant Number mean: 0.0331165 max: 0.168717 Time = 0.00018 Evolving kinematicCloud Solving 3-D cloud kinematicCloud 2 move-collide subCycles HTML Code:
src/lagrangian/intermediate/submodels/Kinematic/CollisionModel/CollisionModel/CollisionModel.H Code:
// Member Functions //- Return the number of times to subcycle the current // timestep to meet the criteria of the collision model virtual label nSubCycles() const; Regards, |
