[vtkusers] Writing exodus metadata with python

[Julian Andrej]

Hello,

i'm trying to write metadata for NodeSets/SideSets to an exodus file 
using vtk. I have all the information i need to describe the NodeSet 
(Cell ids that belong to the NodeSet and the name). Is there any example 
that describes that?

I tried to figure it out myself but came up with some issues. I 
understand that i have to fill a vtkModelMetadata object and call 
vtkModelMetadata::SetNumberOfNodeSets with the appropriate number of 
nodesets. Then i guess i have to set vtkModelMetaData::SetNodeSetSize 
but here is my problem of understanding: Not every nodeset has the same 
size of nodes! Or is it assumed, like in 
vtkModelMetadata::SetNodeSetNodeIdList that the argument for 
vtkModelMetaData::SetNodeSetSize contains a list with the mapping:

entry 0: lengt of nodeset 0
entry 1: lengt of nodeset 1

and so on?

I'd appreciate any help regarding my issue.

Regards
Julian Andrej
