Hello, I have a question concerning PDEs with initial / boundary conditions. Now, I am trying to solve this PDE. The general solution to my PDE is achieved by: governing equation : the homogeneous diffusion equation is > PDE := diff(c(x,t),t)=diff(c(x,t),x,x); the boundary condition are > BC1 := c(0,t)=0; > BC2 := c(0,L)=1; the initial condition is > IC := c(x,t)=1; I want to solve above equation by using maple software(Currently I am using Maple 10). In this case I want to find the final expression. If you have any idea to lead this problem using this software, please help me help.
The following is the code for the 2nd Fick's law with initial/boundary conditions. Unfortunately this code does not show me the result required for next process. It would be useful for us to proceed this work. Thanks in advance. ( Currently we are using Maple 10.) > restart; > DiffusionCoefficientST := 0.5e-2; > ExperienceConstant := 5; > Temperature := 273+25; > PDE := diff(C(x, t), t) = > DiffusionCoefficientST*(exp(1))(-ExperienceConstant(1/Temperature-1/296))*(­diff(C(x, > t), x, x)); > IBCondition := {C(x, 0) = 2, C(0, t) = 0, ((D[1])(C))(5, t) = 0}; > pds := pdsolve(
