I did give Exodus a shot, but it has two shortcomings that prevent me from 
using it: 

--  It does not work with complex numbers (although this can be fixed, given 
some of the discussion last week). On the same note, even VTKIO does not 
recognize complex, numbers, but it does write out the real part. I have created 
a port-processing system with additional vectors defined for the imaginary part 
of the solution, which has been working fine for me. 

--  For some reason, Paraview does not understand the temporal character of the 
file names (a_1.e, a_2.e, a_3.e,…., a_n.e being the n time step values). Once I 
read all of them into Paraview, incrementing the time in its GUI does not 
change anything in the visualization. So, I have to manually select a file 
(a_3.e, for example) to see the output from that time step.  Any suggestions 
here?
