Dear Mike,
Thank you for your answer!
I implemented your suggestions and I don’t have the error anymore. The code
starts running, but then goes crazy with absolutely random values of
composition (as opposed to an expected periodic variation). I don’t know if
this still come from the spline..
I
Hi Clara,
Is your spline function returning a numpy array? I think what is
happening is that FiPy is seeing it as a tensor diffusion coefficient
rather than just a list of the values throughout your simulation. I'm a
little rusty with FiPy these days, but I think you could so something
like
Hello,
I would like to model the Cahn Hilliard equation with a diffusion coefficient
that depends on the cell variable (concentration X) and time.
The diffusion coefficient (Diff) is proportional to the second derivative of
the free energy (d2G), for which I have the values in an external file,
