We would like to solve an FEA problem (unstructured grid) where the nodes on the elements have different dofs. For example the corner nodes have only dof 0 and then mid-side nodes have dofs 0,1,2 (think 8 node serendipity element). This is a multi-physics problem so we are looking to use the fieldsplit features to pre-condition and solve. Is there a simple example of this type of usage in the src that we can try to mimic?
I presume this will take programming as opposed to just setting command line options. -sanjay
