  Hi,
  You should send an ASCII version of your file, in order to check the validity of the values you wrote. For what I can see in you XML vtu, your PointData array named "scalars_" range from 1 to 1. Moreover, I felt surprised to find a mixture of binary data in an XML ascii file... But maybe someone else could give more precision on that.

  Best regards,
  Jerome

    Hi,

    my vtkunstructuredgrid contains only vtkPointData in which there is only a vtkBitArray and all values are 0 or 1.0. There is no other fields.

    Kind Regards

      Oops, keyboard mistake... Let's go on:
      Replacing it by valid values fix my problem.

      HTH,

        Hi,
        I got such a problem, that comes from some -1.#IND or (Not-a-Number, or NaN) values in the fields. Replit by hand with a valid value

          Hi,

          I am writing vtkunsturucturedgrid to a file and then reading it.However, after reading i get nothing: number of cells , number of points all are zero.

          I attached my file.

          My code is :


          vtk.vtkXMLUnstructuredGridWriter w = new vtk.vtkXMLUnstructuredGridWriter(); 

          string ltempFile = System.IO.Path.GetTempFileName(); 

          w.SetFileName(ltempFile); 

          w.SetDataModeToBinary(); 

          w.SetInput(((vtk.vtkUnstructuredGrid)grid)); 

          w.Write(); 



          vtk.vtkXMLUnstructuredGridReader w2 = new vtk.vtkXMLUnstructuredGridReader(); 

          w2.SetFileName(ltempFile); 

          w2.Update(); 
          int num = w2.GetOutput().GetNumberOfPoints();

          Kind Regards
