CFD Online Discussion Forums - read user input value for post-processing utility

Hi all,

I've been able to read input value for a pre-processing utility:

Code:

int main(int argc, char *argv[])  

{  

 

  argList::validArgs.append("value_h");

  argList::validArgs.append("value_b");

  argList::validArgs.append("value_r_c");

  argList::validArgs.append("value_alpha");



# include "setRootCase.H"  

# include "createTime.H"  

# include "createMesh.H"  

# include "createFields.H" 



  const scalar h(readScalar(IStringStream(args.args()[1])()));

  const scalar b(readScalar(IStringStream(args.args()[2])()));

  const scalar r_c(readScalar(IStringStream(args.args()[3])()));

  const scalar alpha(readScalar(IStringStream(args.args()[4])())); 

 

.....

 

return(0);  

}

but when I do the same thing for a post-processing utility named 'trace_max_vor_droite' (based on 'vorticity' utility) it doesn't work.

Here's what I tried:

Code:

void Foam::calc(int argc, char *argv[], const Time& runTime, const fvMesh& mesh)  // Line 41

{



    argList::validArgs.append("valeur Z");

    # include "setRootCase.H"

    const scalar coord_z(readScalar(IStringStream(args.args()[1])()));



....



}

The error message:

Code:

I'm very interested to learn how OpenFOAM works! Help would be very appreciated

Thank you,
