Splits: eliminated a memory leak (addresses #1851).
dkarpeyev commented 10 years ago

Splits is not a way to build a preconditioning matrix (PETSc: Pmat), but to build a preconditioner (PETSc:PC). The most important application of Splits is the control over the (hierarchical) construction of PETSc's PCFieldSplit using (a) mesh adjacency, (b) variables, (c) Contact. In particular, Contact is dynamic, coming and going with the timestep, altering the Jacobian sparsity-structure and necessitating a rebuilding/resetting of the preconditioner.

DMMoose: enable SNES/KSP/PC resetting due to dynamic, Contact-based Splits; addresses #1851.
Always attach DMMoose to SNES to handle BAIJ matrices etc., not only to enable PCFieldSplit.
