[Paraview] CoProcessing with Fortran and ParaView 3.98

[Pettey . Lucas]

Hello everyone,

I am trying to run a simple Fortran coprocessing example with a complex data type. I am following the example here:

http://en.wikibooks.org/wiki/Parallel_Spectral_Numerical_Methods/Visualization_with_ParaView_CoProcessing#ParaView_CoProcessing_Resources

I have written a basic Fortran code that outputs the data in binary, opened that in ParaView, output the coprocessing script and then written the adaptor following the example in the above link. My adaptor looks like:

extern "C" void createcpimagedata_(int* nx, int* ny, int* nz)
{
  if (!ParaViewCoProcessing::GetCoProcessorData()) {
    vtkGenericWarningMacro("Unable to access CoProcessorData.");
    return;
  }

  // The simulation grid is a 2-dimensional topologically and geometrically
  // regular grid. In VTK/ParaView, this is considered an image data set.
  vtkImageData* Grid = vtkImageData::New();

  // assuming dimZ == 1 for now
  Grid->SetDimensions(*nx, *ny, *nz);
  Grid->SetNumberOfScalarComponents(2);

  // Setting the Origin and Spacing are also options.

  // Name should be consistent between here, Fortran and Python client script.
  ParaViewCoProcessing::GetCoProcessorData()->GetInputDescriptionByName("input")->SetGrid(Grid);
}

// Add field(s) to the data container.
// Separate from above because this will be dynamic, grid is static.
// Might be an issue, VTK probably assumes row major, but
// omeg probably passed column major...
// by hand name mangling for fortran
extern "C" void addfield_(double* scalars, char* name)
{
  vtkCPInputDataDescription *idd = ParaViewCoProcessing::GetCoProcessorData()->GetInputDescriptionByName("input");

  vtkImageData* Image = vtkImageData::SafeDownCast(idd->GetGrid());

  if (!Image) {
    vtkGenericWarningMacro("No adaptor grid to attach field data to.");
    return;
  }


  // field name must match that in the fortran code.
  if (idd->IsFieldNeeded(name)) {
    vtkSmartPointer<vtkDoubleArray> field = vtkSmartPointer<vtkDoubleArray>::New();
    field->SetNumberOfComponents(2);
    field->SetName(name);
    field->SetArray(scalars, 2* Image->GetNumberOfPoints(), 1);
    Image->GetPointData()->AddArray(field);

  }
}

I am getting some errors from the Makefile generated by Cmake:

/Users/lucaspettey/codes/BEC/coprocVTK.cxx:40:38: error: too few arguments to function call, expected 2, have 1
  Grid->SetNumberOfScalarComponents(2);

    Image->GetPointData()->AddArray(field);
                                    ^

Any help is appreciated.
