My odessy to update my code to the main branch continues...I am now
encountering an error with VecSetValue:
[0]PETSC ERROR: VecSetValues() at
/Users/sg/petsc-3.22.4main/src/vec/vec/interface/rvector.c:926 Null
Pointer: Parameter # 4
This is on a single processor run -- I got tired of closing all those
debug windows. My call looks like
call VecSetValue(rhs, k-1, b(j), ADD_VALUES, ierr)
and the first two data types are Vec and integer, and for the third
real (kind=8) :: b(:) ! comes through the argument list for the
subroutine
vecsetvalue_ however seems to be receiving va=0x0000000000000000. I see
that formally the value is supposed to be PetscScalar; is that the
issue? The thread backtrace is below.
