[petsc-users] error 2 in QAMD : Schur size expected ...

[Aleksandra Grudskaia]

Dear PETSC team,

Sometimes I get the error

Internal error 2 in QAMD : Schur size expected: 0 Real: 1

And for me it seems that it appears absolutely randomly. In my code I 
use the following petsc files:


#include <petscmat.h>
#include <petscvec.h>
#include <petscksp.h>


In my bashrc file I have:

module load petsc-real-double/3.13.5


Could you please tell, why this error can occur?


Thank you in advance,

Yours,

Aleksandra Grudskaia
