[dsmcFoam+] Crash after mesh change when using sticking wall patch(es)

[timteichmann]

Currently the solver will crash reliably if there are stuck parcels and the mesh is changed (e.g. in a parallel run after load balancing where each processor will have a freshly assigned mesh). In such a case the parcels stuck properties (patch and patch face that a parcel is stuck to) are not valid anymore.

Edit: This happens only if a stuck parcel is desorbed after the mesh has changed. Setting a finite residenceTime is therefore necessary to reproduce the issue.

As there is no simple / elegant way to get a global patch / face identifier in parallel runs and this would also introduce additional overhead, the most elegant solution seems to be to relocate the parcels when the solver is restarted.
