nonlinear source term
Asked by
Abbas Shirinifard
hello, I am trying to solve (transient and steady state) a diffusion equ in a 3D geometry that has multiple domains. Each domain acts as source and/or sink. The equation looks like the following:
dC/dt=D*
where S is 1 in some domains and zero elsewhere, similarly Q is 1 in some domains and zero elsewhere (Q and S can be both 1).
Does FEniCS handle this kinds of discontinuous nonlinear source and sink terms? How much coding should I expect to implement this using FEniCs and DOLFIN?
This kinds of problems are very common in modeling transport in a growing tumor where tumor cells consume nutrients coming out of blood vessels.
comments and suggestions are appreciated!
