[Trilinos-Users] MueLu + Belos + Epetra Runtime Error

[Lin, Shilei]

Dear developers / Users,

I am try to modify an example code from the MueLu packages. I have attahed my source code. The code will compile, however, it won't work when I set the Preconditioner to the Belos linear problem.

In line 152:   //Problem->setLeftPrec(M);

This is the error message from runtime:

terminate called after throwing an instance of 'Belos::EpetraOpFailure'
  what():  /home/shilei/Documents/Source/Trilinos/packages/belos/epetra/src/BelosEpetraAdapter.cpp:816:

Throw number = 1

Throw test that evaluated to true: info != 0

Belos::OperatorTraits::Apply (Epetra specialization): Calling the Epetra_Operator object's Apply() method failed, returning a nonzero error code of -1.


When I disabled preconditioner, the programm actually works.
Also, I can not find an example for using Belos as solver and MueLu as preconditioner with Epetra.


Thanks!
Shilei Lin
