Summary | 0003529: Barycentric tracking in moving meshes seems to show erroneous patch | ||||
Description | Dear team, I am testing the new Barycentric tracking in moving mesh. For that I used the column tutorial with MPPICDyFoam. I used staticFvMesh and a dynamicMotionSolverFvMesh with a extremely low motion. The idea is to use the dynamic tracking functions in the particle.H. Please see the attached videos for both cases. In the moving mesh case. the particle path is quiet erratic. The case is attached. All the MPPIC sub-models are off. And a single particle is injected. I've debugged the tracking algorithm, while I can make sense of the static mesh tracking , the moving one is a bit more challenging as I don't have any reference from where this formulation comes. I could dig more into this if I had some reference to follow. Thanks | ||||

MPPICDyMFoam hasn't existed since version 6. It was deleted when dynamic mesh support was added to MPPICFoam, and then recently DPMFoam and MPPICFoam were replaced by denseParticleFoam. I can't run your case. Obviously it doesn't run in dev, but even using MPPICDyMFoam in versions 5 and 6 your case doesn't run. Which version of OpenFOAM are you using? |

Hi Will, I am using a combination of different versions which best fit my needs. As you can see I used the column tutorial which now under denseParticleFoam. I haven't pulled the latest dev as there are too many changes to track. But , I am tracking all the new bug fixes in the lagragian particle tracking library. After a few test/debug making the column tutorial to use dynamicMesh gives some erroneous particle path. I am quiet sure the problem lies in trackToMovingTri. I pulled the latest changes to handle detA < 0. In the tutorial I switched all the MPPIC sub-models off and I just do the tracking. Thanks |

It works fine in dev and 8. See attached. I would assume that you have made a mistake in creating "a combination of different versions which best fit my needs". Closing. |
