Hi all I have a laplace-type problem that's physically built from repeating instances of the same block. I'm creaing matrices for the individual blocks, and I'd like to reuse the individual block matrices in order to compose the complete problem. (i.e if there 10K instances of 20 blocks, I'd like to build 20 matrices, then use them to compose the large complete matrix) Is a 2D DA the right object to do that? And if so, where can I find a small example of building the DA object in parallel, then using the different (for every instance) mappings of local nodes to global nodes in order to build the complete matrix?
