[petsc-users] MAT_NEW_NONZERO_LOCATIONS working?

Tue, 29 May 2018 01:32:32 -0700 


Hi,
 
I tried to set MAT_NEW_NONZERO_LOCATIONS to false, as far as I understood 
MatSetValues should simply ignore  entries which would give rise to new nonzero 
values not creating a new entry and not cause an error, but I get  "[1]PETSC 
ERROR: Inserting a new nonzero at global row/column". Is this option supposed 
to work or not?
