Hi, I'm getting a segmentation violation error when I use DMCompositeGetISLocalToGlobalMappings on a DMComposite defined redundantly on subsets of the PETSC_COMM_WORLD. I could reproduce the error in the small code you can find here attached. It creates a PetsSubcomm from PETSC_COMM_WORLD, then it defines a DMDA on the Subcomm->comm and finally it packs it into a DMComposite. I get this error whenever I call DMCompositeGetISLocalToGlobalMapping on a DMComposite defined in such a way.
I would be glad if you could give it a look. Thank you Domenico -------------- next part -------------- A non-text attachment was scrubbed...
