[vtkusers] How to use the vtkLSDynaReader class to handle FEM data in LSDYNA database

[Viet H.Q.H]

Dear David,

Thank you for your information. I have removed the
vtkStructuredGridOutlineFilter and referred to
"VTK/Graphics/Testing/Cxx/TestMultiBlock.cxx" to rewrite the code:


    string dir="/home/viet/vtk_test/taylor/";
    plLD->SetDatabaseDirectory(dir.c_str());
    plLD->Update();

    vtkMultiBlockDataSet* mbds = plLD->GetOutput();

    vtkCompositeDataGeometryFilter* geom =
vtkCompositeDataGeometryFilter::New();

     geom->SetInputConnection(0, mbds->GetOutputPort(0));

    vtkShrinkPolyData* shrink = vtkShrinkPolyData::New();
     shrink->SetShrinkFactor(1.0);
     shrink->SetInputConnection(0, geom->GetOutputPort(0));

     vtkPolyDataMapper* shMapper = vtkPolyDataMapper::New();
      shMapper->SetInputConnection(0, shrink->GetOutputPort(0));
      vtkActor* shActor = vtkActor::New();


Since the class "vtkMultiBlockDataSet" has no member named "GetOutputPort",
I get a error message for

geom->SetInputConnection(0, mbds->GetOutputPort(0));

Should I find a way to convert a vtkMultiBlockDataSet object to  an
vtkXMLMultiGroupDataReader object in order to use
vtkCompositeDataGeometryFilter?

Thank you in advance for your help.
Best,

Viet.
