Erkin,
Please take a look at the conversation at

that discusses the issue. You might be able to compile by going back
to the older version as mentioned in the comment.
Alternatively, you could disable Trilinos explicit

Hello everyone. I am trying to plot load displacement curves for an
elasticity problem.
For this I need to extract the non-zero elements of my sparse stiffness
matrix. I tried something like system_matrix[I][j] to extract the ij-th
entry but it seems this doesn't work for the SparseMatrix.
