[Trilinos-Users] issue on extracting view from FEVbrMatrix

[Williams, Alan B]

Andrea,
Perhaps you're extracting a view of a block that resides on a different processor?
After GlobalAssemble is called, the data is moved to unique processor ownership as described by the Epetra_Map that the matrix was constructed with.

Subject: [Trilinos-Users] issue on extracting view from FEVbrMatrix

hi,
I have an issue when extracting a view from FEVbrMatrix; the code is the same
I showed previously, after having assembled a FEVbrMatrix I extract a view of a
3x3 SerialDense matrix.
This matrix prints fine but when I try accessing the second column
elements it fails with segmentation
fault.
See working code here:
https://gist.github.com/834803

the output of the code is in the comments.
thanks,
andrea zonca
