[Paraview] Tensor variables in ExodusII database

[Timothy Jesse Fuller]

Thanks for the reply Sam.  I made a typo in my original question - I did have the off-diagonal components labeled as you suggested.  I tried swapping x and z in the last off-diagonal term to see if that would make a difference - to no avail.  Interestingly, ParaView does seem to interpret the variable as a tensor, as indicated in ParaView re-ordering the components from how they are written to the database.  e.g. ParaView lists them as _xx, _xy, _xz, _yy, _yz, _zz but they are written to the database as _xx, _yy, _zz, _xy, _yz, _xz (or _zx) - as shown in attached screen shots.

I seem to recall opening ExodusII files with tensors displayed in a “collapsed" fashion - with the magnitude being the default view, just as Displacement in the attached screen shots.  Any further advice to reproduce this behavior is much appreciated!

Cheers,

Tim,

Tribal knowledge leads me to suggest trying

var_xy, var_yz, var_zx

for the off-diagonal terms.

(I can't recall for sure but the last entry may be var_xz)

When writing a symmetric tensor to an ExodusII database, the following link indicates that ParaView will interpret the variable as a symmetric tensor if it is written to the file as var_xx, var_yy, var_zz, var_xy, var_xz, var_yz, where var is the variable name

http://www.paraview.org/Bug/view.php?id=5979

However, when I write symmetric tensors to the database with the above convention, ParaView interprets them as 6 independent scalars.  Is there a more updated method of naming symmetric tensors in ExodusII database files so that ParaView will interpret them correctly?

Cheers,
