<P>
I have a very large Multi-block EnSight files (16 million cells, more than 2GB disk space) which I want to visualize using ParaView on a Linux cluster. Since paraview does not have a Parallel EnSight reader, it fails to read and load the file even while running on a parallel mode. So I have decided to write a small vtk script which will read the EnSight file and write it into an Exodus file. Here is the script for that<BR>
<BR>
import vtk<BR>
<BR>
reader = vtk.vtkEnSightGoldReader()<BR>
reader.SetCaseFileName("ensight.case")<BR>
reader.Update()<BR>
<BR>
writer = vtk.vtkExodusIIWriter()<BR>
writer.SetInputConnection(reader.GetOutputPort())<BR>
writer.SetFileName("exodus.ex2")<BR>
writer.Write()<BR>
<BR>
When I run the program I get the following error :<BR>
<BR>
raashid@ICC-PUNE-DSK-20:~/EnSight$ python ensight_exodus_old.py <BR>
ERROR: In /build/buildd/vtk-5.0.3/Filtering/vtkStreamingDemandDrivenPipeline.cxx, line 557<BR>
vtkStreamingDemandDrivenPipeline (0x81bf808): No maximum number of pieces has been set in the information for output port 0 on algorithm vtkEnSightGoldReader(0x82d6810).<BR>

Even though an exodus file is generated but the resulting geometry is incomplete. Please suggest me how to eliminate this error and convert the EnSight file properly.
