[petsc-users] Allocating memory for off-diagonal matrix blocks when using DMComposite

[Gautam Bisht]

Hi,

The comment on line 419 of SNES ex 28.c
<http://www.mcs.anl.gov/petsc/petsc-current/src/snes/examples/tutorials/ex28.c.html>
says
that the approach used in this example is not the best way to allocate
off-diagonal blocks. Is there an example that shows a better way off
allocating memory for off-diagonal matrix blocks when using DMComposite?

Thanks,
-Gautam.
