that can get rid of those zeros in the matrix generated based
on the stencil information?
Thanks very much!
Best regards,

Hello all,
This is a test for np=1 case of the nonzero structure of the jacobian matrix.
The jacobian matrix is created via
ierr =
DMDACreate2d(comm,DMDA_BOUNDARY_NONE,DMDA_BOUNDARY_NONE,DMDA_STENCIL_BOX,
parameters.mxfield, parameters.myfield, PETSC_DECIDE, PETSC_DECIDE, 4, 2, 0, 0,
);CHKERRQ(ierr);
ierr = MatSetOption(jacobian, MAT_IGNORE_ZERO_ENTRIES,
PETSC_TRUE);CHKERRQ(ierr);
nothing changed.
The version is 3.1-p8.
Thanks very much!
Best regards,
Rebecca

Are you sure your entries are exactly 0.0?
Yes, because I have looked at the output, they are 0.00e+00.

I have a piece of code that need to store the RHS vector b of the ksp object

However, the routine is like:

ierr = DMMGSolve(dmmg);CHKERRQ(ierr);

-ksp_view_binary?
This will save all the ksp content in binary form (more than one set of
jacobian and rhs), if I only want to save the first initial Jacobian and rhs,
will let -ksp_max_it 1 -snes_max_it 1 give me that?

Hello all,
Is there any sample matrix and rhs data files for the test of ex10.c?
You can get some sample datafiles [mat,vec
. After the solver works well and you know the matrix structure
should not change,
then use SAME_NONZERO_PATTERN for optimization.

This will specify the nonzero pattern as the same? How could I check if I have
set this up right?

Hello,
I would like to use SuperLU as a direct solver for a large size problem running
on multiple processors.
I have write the analytical Jacobian via FormJacobianLocal(), however, I do not
know how to set the direct solver.
Any thoughts?
Thanks a lot!

Dear all,
I have assembled a 2d matrix through the FormJacobianLocal() routine.
I would like to store this sparse MXN matrix A in the following form:
line1: M N numberofnonzeros
line2: i j value
line3: i j
Hi Jed,
I need to have this form for the simple input for PDSLin.
What do you mean by COO?
Any examples to show how to pull that new array for reading from the AIJ
structure?
Thanks a lot!

What do you
/impls/aij/mpi/mumps/mumps.c
which convert petsc seqaij and mpiaij to triples: row[], col[], val[] .
You may take a look at these routines.
