CFD Online Discussion Forums - Initializing constants

Hello,

I'm looking for a solution of my OpenFOAM problem.

I have defined constant dimensioned scalars and vectors in the transportProperties dictionary, eg:

HTML Code:

Sct        Sct      [0 2 -1 0 0 0 0] 2.0e-09;

g           g         [ 0  1 -2  0  0  0  0] (0 0 9.81);

The class looks like this:

HTML Code:

# include "IOdictionary.H"

class A

{

  const IOdictionary transportProperties_;

  const dimensionedScalar Sct_;

  const dimensionedScalar g_;

public:

  A;

}

The constructor looks like this:

HTML Code:

A::A

 :

 transportProperties_( IOobject(

     "transportProperties",

     U.time().constant(),

     U.db(),

     IOobject::MUST_READ,

     IOobject::NO_WRITE)),



  Sct_ ( dimensionedScalar( transportProperties_.lookup("Sct") ) ),

  g_    ( dimensionedVector( transportProperties_.lookup("g") ) )

{}

The compiler doesn't report any bugs, but when I try to run a testcase the following error is displayed during the constructor call

Segmentation fault

Can someone please tell me the error in my program?

Thank you very much.
