Hello all,
I ran FiPy under RedHat 5 to solve 4th-order PDE with anisotropic diffusion
coefficient and periodic boundary in 2D model. During the first few steps, it
shows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------

I guessed there are four errors. But, I'm not sure how to fix it. Can someone
explain me what's the meanings about these messages? Or, I can not solve the
anisotropic diffusion coefficient under periodic boundary? Thank you so much
for any help.
