[petsc-users] DMDAVecGetArrayDOF for read-only vectors

[Claudio Tomasi]

Dear all,
I would like to ask whether there's an analogous of the routine DMDAVecGetArrayDOF for read-only vectors.
I'm using the SNES solver and in computing the SNESfunction I need to read and use the values of the solution vector x, which is created with DMCreateGlobalVector where the associated DM has two dofs per node.
Best regards,
Claudio Tomasi
