[Trilinos-Users] NOX warnings

[Roger P. Pawlowski]

Hi Mohammad,

You can turn off the warnings by removing the warnings option from the 
"Printing" parameter sublist.  For example, the following code can be 
found in the file Trilinos/packages/nox/test/epetra/1Dfem/1Dfem.C for 
setting the output information:

Teuchos::ParameterList& printParams = nlParams.sublist("Printing");
  printParams.set("MyPID", MyPID);
  printParams.set("Output Precision", 3);
  printParams.set("Output Processor", 0);
  if (verbose)
    printParams.set("Output Information",
                 NOX::Utils::OuterIteration +
                 NOX::Utils::OuterIterationStatusTest +
                 NOX::Utils::InnerIteration +
                 NOX::Utils::LinearSolverDetails +
                 NOX::Utils::Parameters +
                 NOX::Utils::Details +
                 NOX::Utils::Warning +
                             NOX::Utils::Debug +
                 NOX::Utils::TestDetails +
                 NOX::Utils::Error);

Remove the line " NOX::Utils::Warning +" and it will disable warnings. 

Alternatively, you can redirect all nox output by assigning a different 
ostream for output.  NOX accepts two ostreams, one for normal output and 
one for errors.  A quick glance through the code shows that warnings are 
sent to the normal output stream and not the error stream.  So you will 
have to redirect all nox output to the same file if you want to hide the 
warnings this way.  All output in nox is controlled by the NOX::Utils 
class.  You can find more information here:
