Hi Varun and Francesco,

I'm unable to read any block, except the first, in multiblock
PLOT3D files.
I can reproduce this bug with any multiblock PLOT3D file having more
than one block. For instance we can consider the test case I prepared
for bug #400406 (see [1] and [2]).
Mayavi2's current plot3d support is very basic and does not support any
multi-block data. This is a feature request and I would certainly
appreciate it if you filed a ticket on the trac instance.

The test data is useful thanks. I'll keep a copy just so it can be used
when I get to implementing the multi block support.
OK, back to the PLOT3DReader tab: where's the option to select which
grid blocks I want to load?!?
I really cannot find it...
Because it isn't implemented yet. :(
I would like to have a means to decide which grid blocks will be loaded
(e.g.: I want to load block 1, 2, and 4, but not the remaining two),
so that a number of PLOT3D:tiny.xyz, tiny.q objects are automatically
created, each one corresponding to one of the requested grid blocks
(e.g.: three objects are created, corresponding to blocks 1, 2, and 4).
The trouble with this approach is that it breaks down when you have 100
blocks. How do you view 100 of them? Anyway, this is something that
would require some thought and work.
Please note that this decision may be taken only after PLOT3D properties
(such as "Binary file", "Has byte count", and so forth) have been
specified, or otherwise the total number of blocks present in the
PLOT3D file will not be computed correctly...
Correct.
Thanks for this detailed report. It looks more like a wishlist
bug. I'm forwarding this upstream.
Yes, that is correct. If you can add a ticket on the trac interface here,
http://svn.enthought.com/enthought/
that would be great, if not I can add it (just let me know either way).
Thanks.
cheers,
prabhu
