Efficient way to read a lage mesh?

[Ulrich Uphoff]

Hi All,

what is the most efficient way to restore an unstructured
grid from a file?

for a 16250 cell mesh I used

  vtkUnstructuredGrid aHexahedronGrid
  aHexahedronGrid Allocate 130000 130000

  vtkUnstructuredGridReader gr
   gr SetFileName $filename
   gr Update
   aHexahedronGrid CopyStructure [gr GetOutput]

but isn't that wasting time and space? Is there a better way?

Greetings
Uli
