[petsc-users] Question on PetscViewerFileSetMode

Hello team,

I recently updated by PETSc version and this error emerged:
"Cannot change mode to APPEND after setup"

I used to  use PetscViewerFileSetMode to set the mode as WRITE when I first
initiate the file, and for following time steps I set it to APPEND to open
the existing file and append data. Has the functionality changed?


Best regards,
