the gradient. You can get my tweaked adaptivity_ex4 from:

Ata,
Are you sure you need Nemesis? This should really only be necessary once
you get up over ~200 million DoFs or so. Anything smaller than that should
work fine with Exodus.
Not saying you haven't found a bug here... just trying to make sure you're
not overly burdening yourself with extra wor

Possible, but not necessarily.

This is part of your (our) problem, I'm afraid: we don't output any
shape functions more interesting than C0 quadrati
Roy,
1st as always thanks for the quick response.
I see what you mean. And no I didn't I did the gradient calculation in VisIt. I
don't use/calculate this gradient in my code.
Here is the reason I suspected gradients:
the problem I'm solving is complicated but in short what I solve for is a

Dear all,
I found a potential bug with Clough elements. I'm solving a 4th order
problem using C1 Clough elements and when I plot magnitude of gradient of
the solution I found out that it is discontinuous on mesh partition
boundaries. I would appreciate if any comments.
Thanks,
Ata
