|Summary||0003142: Erroneous Tracking of Stick Lagrangian Parcels|
the number of parcels, which stick to a patch, is not counted correctly. This happens when using a lagrangian-based solver in combination with "stick" patch interaction models. It seems, that for each lagrangian sub-iteration per time step, the parcels are tracked resulting in multiple stick detections per time step per parcel.
|Steps To Reproduce||1) Take the aachenBomb tutorial for sprayFoam|
2) Change the standardWallInteractionModel to "stick"
3) Set "heatTransferModel" and "phaseChangeModel" to "none" (optional)
4) Shorten the domain to decrease the CPU time (optional)
5) Run sprayFoam
The solver output will reveal a huge number of stick parcels:
Parcel fate: patch (number, mass) walls
- escape = 0, 0
- stick = 9511243, 0.00527835
However, the injector model reveals:
- parcels added = 6745
- mass introduced = 3.68561e-06
So more parcels are detected for "stick" than are actually injected.

This seems similar to the report #3084: https://bugs.openfoam.org/view.php?id=3084
Which exact commit/date of the build of OpenFOAM 6 are you using? In principle, you can find it by running this command:
For example, for me the Deb package installation on Ubuntu 16.04 gives me "6-f934eabb0d52".
I was using the following version: 6-e05f780ebc87. However, updating to the latest git version resolves this issue.
Sorry for the inconvenience. This ticket can be closed.
||Already resolved in dev by commit c17e6dbfe, and in version 6 by 166e3a7a1|
