There may be something wrong with the file. Opening it in ParaView
crashes ParaView.

Both of these casts end up NULL:

  vtkSmartPointer<vtkLSDynaReader> reader =
    vtkSmartPointer<vtkLSDynaReader>::New();
  reader->SetDatabaseDirectory("/home/doriad/Downloads" );
  reader->UpdateInformation();

  vtkUnstructuredGrid *ug =
vtkUnstructuredGrid::SafeDownCast(reader->GetOutput()->GetBlock(0));
  std::cout << ug << std::endl;

  vtkPolyData* pd = vtkPolyData::SafeDownCast(reader->GetOutput()->GetBlock(0));
  std::cout << pd << std::endl;

Do you know what type the data is supposed to be?
