[MOAB-dev] Questions about Tags and Topology

[Christopher Mueller]

Alright – then it was probably working but the '1' I was assigning to [1,1] was being set to '7' under the hood, so I wasn't seeing the change because I still had the 'workaround' patch applied (meaning the table was starting with [1,1]=7).

All seems to be working as expected now!

Thanks Jim,
Chris

Ahh – ok.  I almost had it – I tried setting adjTable using a whole
4x4 numpy.array - but I neglected to try using a whole 4x4 python
array.

That should work:

mesh = iMesh.Mesh()
adj = mesh.adjTable
adj
array([[7, 4, 4, 1],
       [1, 0, 5, 5],
       [1, 5, 0, 5],
       [1, 5, 5, 7]], dtype=int32)
adj[1,1] = 1
mesh.adjTable = adj
mesh.adjTable
array([[7, 4, 4, 1],
       [1, 7, 5, 5],
       [1, 5, 0, 5],
       [1, 5, 5, 7]], dtype=int32)

However, note that when you set the adjTable, you won't necessarily get
the same thing back. The table is modified to use whatever works best
for MOAB while still meeting your requirements, if possible.

Also, you can use the enum values in iBase to refer to these, e.g.
iBase.AdjCost.unavailable.
