[Paraview] CoProcessing with Fortran and ParaView 3.98

Hi Andy,

I have attached a tar file with all 3 source code files, the Python script and the CMakeLists.txt file used to build the executable.

Thanks so much for helping with this.

Lucas

Hi Lucas,

Could you send me your CMakeLists.txt or your Makefile used to build this?

I think I should be able to diagnose the problem fairly quickly in a debugger.

Also something weird that I have noted.

The "Initialize Helper Script" line prints twice when I run the Fortran code and no print statements anywhere in my Python script execute (not even if they are at the top).

When I run the C++ example located here: http://www.itk.org/Wiki/Coprocessing_example, the "Initialize Helper Script" only appears once and print statements in the Python script execute normally.

I'm not sure if this helps or makes things worse.

Thanks,
Lucas

Nothing printed at all.

Does anything special have to be done during the compile/link steps for the python script to work properly?

Thanks,
Lucas

How about trying:
psi01_.UpdatePipeline()
print psi01_.GetDataInformation().DataInformation.GetNumberOfPoints()

right about where the writer was created. This will give print out the number of points in the data set that you have.

Hmm, how about trying replacing those two lines with:
    ParallelImageDataWriter1 = CreateCPWriter( XMLPImageDataWriter, "fullgrid_%t.pvti", 1, cp_writers )

Let me know how that goes.

If not, I think we'll need to put some print statements in there.

Did you also include the w.UpdatePipeline() part after the writer was created? It won't create the file unless that's in there.

Hi Andy,

Changing to Scalars=['POINTS','psi01'] did not change anything. I still get the same error and blank image.

I tried adding the XMLPImageDataWriter command, but no file 'fullgrid.pvti' was produced so I can't tell what is being populated into the grid.

I hardwired the C++ adaptor to 'psi01' rather than the character array name in case their was a problem with the way the string was passed. I had checked that name contained the correct characters, but I figured hardwiring would be safer at this stage.

Anything else that you think I should try?

Thanks,
Lucas

Subject: Re: [Paraview] CoProcessing with Fortran and ParaView 3.98

I think the problem is that:
Clip1 = Clip( guiName="Clip1", InsideOut=0, Scalars=['POINTS', ''], Value=95.0, UseValueAsOffset=0, Crinkleclip=0, ClipType="Scalar" )

Should probably have the name of the point data field set in it. Do this with (assuming psi01 is the name of the field you want to clip with respect to:
Scalars=['POINTS', 'psi01']


My guess is that the scalar field isn't getting set properly. Try adding in:
w = XMLPImageDataWriter(Input=psi01_, FileName = 'fullgrid.pvti')
w.UpdatePipeline()

right after the CreateProducer() method to see what's in your grid.

By the way, does adding in the "//char(0)" work for converting Fortran strings to C/C++ strings (e.g. in "call addfield(psi,"psi01"//char(0))") ? If it does, will it also work for Fortran77? That's a neat little trick!

So after some troubleshooting it seems that C++ doesn't like the complex data type the way Fortran is sending it.

The code runs when I just send a real value. Images appear, but of course they are meaningless since it isn't the correct data. I may try passing the real and imaginary separate. I may also look into row/column order issues although this grid is 100x100x100 so it shouldn't affect anything.

Here is the error that I am receiving.

I know that it is initializing ok and failing at the first call to the co-processor. I have attached my python script output as well as my test code and adaptors.

Hi Lucas,

Can you share your co-processing script and any run output? There may be warnings in the output or info in the script that will help figure that out.

Thanks,
Andy

Hi Berk,

Thanks for the help.

I found that this example is written based on an earlier version of VTK so some of the function calls have changed. Based on your advice and some of the examples contained in the ParaView wiki, I have gotten it to compile and run.

Now I just have to figure out why it isn't generating any VTK objects....

Probably something wrong with my python co-processing script.

Thanks
Lucas

You can simply delete this line:

Grid->SetNumberOfScalarComponents(2);

It is redundant given the following later:

field->SetNumberOfComponents(2);

You also need to #include <vtkSmartPointer.h>.

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
