The Information Tab for HyperTreeGrids are incorrect
We have a dataset that is a multiblock dataset that has two blocks. The first block is the mesh, and can be loaded as either HTG or unstructured grid (UG). The second block has some tracer data.
The problem is that when loading as HTG, the Information tab will load variables and ranges for the second block. This is for when "Multi-block Dataset" is highlighted in the Data Hierarchy box. Ordinarily, when "Multi-block Dataset" is highlighted, the information for the first block in the dataset is shown. This is the case when the data is loaded as UG, the Information tab shows data about the first block.
At first I thought the ranges for HTG were just wrong, but if you click on "Hyper-tree Grid" below "Multi-block Dataset" in the Data Hierarchy box, then you see the correct values.
So in summary: When loading data as HTG, the data in the Information tab is not what you expect, and it's confusing. Is that the responsibility of the reader? Or something in the GUI?
Dataset I'm talking about: todd2_small.tar.gz.
Below are screenshots. The first one shows what loading as HTG looks like, and the second one shows what it looks like when UG is loaded. Notice the different ranges for the variable tev.
Old Description -- ignore stuff below this line
We have come across a problem where the Information Tab will not show correct ranges for variables for HyperTreeGrids. @patchett2002 @demarle From an email from Pat Fasel:
The problem with HTG is that the geometry and data is stored by HyperTree. The reason for that is within a parallel HyperTreeGrid, complete HyperTrees must stay together. So the reader and writer deal with things in units.
In the todd problem which is 12 x 2 x 2 there are 48 HyperTrees and so 48 DataArrays of "tev" and 48 ranges. So if you examine all 48 you will find the correct min and max as it appears in the UnstructuredGrid, but in different HyperTrees.
