These could be used to extract a subset of vector entries for a "multi-physics" preconditioner Many br
Use DMCompositeGetLocalISs() for index sets in the packed local numbering, and Many brDMCompositeGetISLocalToGlobalMappings() for to map local sub-DM (including ghost) indices to packed global Many brindices. Many br
The output argument 'is' must be an allocated array of sufficient length, which can be learned using DMCompositeGetNumberDM(). Many br
