[MOAB-dev] Questions about Tags and Topology

[Christopher Mueller]

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.

This is perfect – no need to set individual elements from my perspective! :)

Thanks again,
Chris

Hi Jim,
I've grabbed revision r5398 and re-installed pytaps.  The error I was
getting before ("AttributeError: attribute 'adjTable' of
'itaps.iMesh.Mesh' objects is not writable") no longer occurs (which
suggests that the re-install worked), I still seem to be unable to
modify the values of the table.  Am I doing something foolish?

You'll need to set the whole table, like so:

mesh.adjTable = [[0,0,0,0], [0,0,0,0], [0,0,0,0], [0,0,0,0]]

Currently, you're getting a *copy* of the adjTable and changing the
values, which won't affect the original. If there's a lot of demand for
setting individual elements of the adjTable, I can add that, but it's
quite a bit more complicated than what I have now.
