Hi,

How to get the offset in global vector for the points not owned by this processor? I have a parallel DMPlex and a section assigned to it. GetSectionGetOffset with a global section returns -1 for the points not owned by this processor.

The easiest way to get it is to use DMGetLocalToGlobalMapping() to map the local offset. This is constructed from the global section, because it stores the global offset as -(offset+1). Thanks, Matt

Thanks, Josh
