Hello Barry, Matt, Jed,

I have just installed the latest and greatest version of petsc and I am hitting a problem I did not have in previous releases.

Here is the error:

[1]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------
[1]PETSC ERROR: Object is in wrong state
[1]PETSC ERROR: Not for unassembled vector, did you call VecAssemblyBegin()/VecAssemblyEnd()?
[1]PETSC ERROR: WARNING! There are option(s) set that were not used! Could be the program crashed before they were used or a spelling mistake, etc!

the vector x I am filling is created with: 
  • call VecDuplicate(this%rhs, x, ierr)
rhs is allocated and I called VecAssemblyBegin()/VecAssemblyEnd() on, do I need to call it on duplicated vectors as well now on?

Only if you change the values. Can you show the entire stack from the error message?

  Thanks,

     Matt
 
Thank you!
