Hello, I'm new to Fipy (and Python generally) and have two basic questions.
1) How does one solve for a triple derivative? The convection term can be used for a first order derivative and the diffusion term can be used for a second order (or any even ordered) derivative. But I can't find a single example where a PDE involving a third order derivative is solved. Combining a convection within a diffusion term (or vice-versa) isn't working. 2) Secondly, can FiPy solve a PDE with complex coefficients? When I set a coefficient to an imaginary value (using j), it seems to simply ignore the entire term, suggesting that it only takes the real part of the PDE and then solves it. I'm using version 2.1.3 of FiPy on version 2.6 of Python. I'd be grateful of any insight that can be provided. Kind regards, Altan
