By default, the byte offset used with the appended data format is UInt32. I
believe that’s where the sizeof(int) is coming from. This default is

Can you share a reproducer? I think I recall the format requiring certain
things to be Int32.

Thanks for the note.
I understood that PETSc calculates the offsets for me through "boffset"
variable in plexvtu.c file. Please correct me if it is wrong.
If plexvtu.c has a bug, it could be around "write file header" part in
which the boffset is also computed. Is this correct? I am not using comp

The calculated offsets are not correct I think.

I have created an MR that documents this and moved the error checking to a
more appropriate location https://gitlab.com/petsc/petsc/-/merge_requests/6070

Hi Matt,
So I have done some research these days and I have found out that I might
try to assemble the SIMPLE for Schur approximation (myS = A11 - A10
inv(DIAGFORM(A00)) A01).
Reading papers around, I come up with a doubt, which I believe to be a very
silly one but worth asking...
Is the way the
I was trying to modify the header flags from "Int32" to "Int64", but the
problem was not resolved. Could I get any additional comments?
Thanks,
Mike

Hello,
I am solving the Navier-Stokes equation and an advection-diffusion equation
to model the temperature. They are fully coupled because the viscosity is
temperature dependent. I plan to solve the fully-coupled problem with a
segregated approach: I first solve the Navier-Stokes equation for a f
Hello Matt,
After some discussions elsewhere (thanks @LMitchell!), we found out that
the problem is that the fields are setup with PCSetIS, without an
attached DM, which does not support this kind of nesting fields.
I would like to add this feature, meaning that during the setup of the

Dear all,
I hope this email finds you well.
We are currently working on a solver which is employing DMDA with SNES.
The jacobian is computed via FDColoring, ie:
call DMDACreate1D(PETSC_COMM_WORLD, DM_BOUNDARY_GHOSTED, NY, NC, NGc,
PETSC_NULL_INTEGER, dmF, ierr)
! - Some steps ...
