Question #697433 on Yade changed:

Robert Caulk proposed the following answer:
Although looking at source [1] this may not be an issue anymore. What
you should try is to set flow.updateTriangulation=True each time you
remove a body. i.e. you should be able to delete particles without
reinstancing a new FlowEngine. As far as I can tell the
setPositionsBuffer is already updated every step and accounts for
deleted bodies, and then it is used for triangulation when a triangulate
flag is set.
