Hi,
I am reading from a binary file of the previous solution and would
like it to be my initial guess.
However, I found that the "-vecload_block_size" is shown in the
PetscOptionsTable, I did not explicitly state this one in my options
file, why it shows up in it? And the block size has been assigned as
"4".
Thanks!
Rebecca
Here is this PetscOptionsTable:
