[petsc-users] Set the directory of output file

[Likun Tan]

Hello,

I want to create and write my simulation result in a binary file called result.dat, but I want to set my file in a different folder, say /home/username/output

I am using

PetscViewerBinaryOpen(PETSC_COMM_WORLD, result.dat, FILE_MODE_WRITE, & view)

But this will create the file in the current folder by default. How could I modify the command to set a new path? Thank you.
