[petsc-users] a fieldsplit question

Hi PETSc team: Suppose I provide three index sets {0}, {1,3}, {2} for PCFieldSplitSetFields to construct a field split PC. Conceputally, the matrix is split into 3x3 blocks. Is it true that the index set {0} always corresponds to the block with index 0? What is the block index for the sets {1,3}?

[petsc-users] how is PETSC_MAX_PATH_LEN defined?

Hi: I am reading http://www.mcs.anl.gov/petsc/petsc-current/src/mat/examples/tutorials/ex9.c.html I am curious about the value of PETSC_MAX_PATH_LEN. Thanks, Ju -- next part -- An HTML attachment was scrubbed... URL:
