The cloud types in OpenFOAM have diverging API (especially when handing parcel data) hence no generic solution for cloud load balancing is possible. However this has been on the Backlog for some time, and I opted for the next best thing:
This PR also provides an alternative route for LB support: function objects. The aim is to make the load balancer more friendly to cases which already have a dynamic mesh type in effect (eg. mesh motion solvers... etc)
For now, this is highly experimental and will get merged only so progress on other fronts can accelerate.
The
particleInjection2Dtutorial case provides a basic exampleparallel-cloud-lb.mp4
While the
MPPICcolumncase showcases the integration of the function object into a mesh motion case:column.mp4
