Hi Gourash,

I think that there may be an error in one or more of your equations.

Cs(1,0)=CS0

2

Cs(1,0)=0

Obviously give contradicting boundary conditions.

Thank you for pointing out the inconsistencey in ICs. Attached is a new xmcd. I have combined the variables and all my equations are with respect to Cs. I am not sure if the syntax of Ct (1.t) is allowed. I am still getting error in Pdesolve statement.

Help Please!. Thanks.

You may check your equations again.If you disable the third equation, Mathcad finds a solution!? I would have expected the system to be underdetermined then.
