[Paraview-developers] [EXTERNAL] Groups of blocks

[Moreland, Kenneth]

I think at some point the Exodus reader did support assemblies like you describe through XML metadata files. I don’t think it got used, and it is probably defunct by this point.

At any rate, the VTK multiblock structure should support assembly hierarchies just fine. I would think it would be easy enough to support them in the Exodus reader if the Exodus reader library supported it.

Subject: [EXTERNAL] [Paraview-developers] Groups of blocks

I had a user come into my office yesterday.  He has been asking the different code teams if we could modify the Exodus spec, and the tools, to allow holding parts within parts, or groups within groups, or sub-blocks within blocks.  My poor choice of words.  Here is an example.

He would like to have a dataset called “car”.  Within the car is a block or group called an Engine.  We could only load the block engine.  Under this would be sub-blocks called pistons, head, connecting rod, etc.  Now, you could turn on and off these subparts.

The questions are first, is this valuable and worth the effort?  Second, if we had a spec from Greg Sjaardema, how much effort would this be?

Thanks,

Alan
