Dear Experts,
my reader read many files by parallel and all data will be converted into vtkPolyData then add into vtkMultiBlockDataSet, it works OK, but sometimes, paraview report below error:

ERROR: In paraview\VTK\Common\DataModel\vtkDataObjectTree.cxx, line 377
vtkMultiBlockDataSet (000001D72A9B4E20): Structure does not match. You must use CopyStructure before calling this method.

Why it pop this error?
How to solve it?

Best Regards,
Sharon
