Dear all, I'm working on some monolithic and partitioned schemes of FSI problem. In a monolithic scheme, the matrix usually consists both fluid and structure parts. However in a partitioned scheme, we can use two matrices which represent the fluid and structure separably. I would like to extract the fluid part and the structure part from the matrix assembled in monolithic scheme. So is it possible to extract some blocks from a sparse block matrix and then use these blocks to build a new sparse block matrix? If yes, this would help me test kinds of partitioned schemes without making too much effort on coding.
For example, A is a 4*4 sparse block matrix with 16 blocks, can I extract the block(0,0), block(0,2), block(2,0) and block(2,2) from A? Even more, can these four blocks be used to build a new sparse block matrix B? Thanks.
