Hi, I am trying to solve the following pde with initial condition CA(0,r)=0 and boundary conditions CA(t,0)=F(t) and CA(t,5)=0.
, where D_A and gamma_A are known constants.
I tried using pdepe but was told that left boundary condition would be ignored when m=1 (cylindrical symmetry).
Then I tried discretizing space variable r before using ode15s, but was confused about how to construct the equation exactly.
Can anybody help?
