jia11(金币+20):Thanks very much. For this equation, no analytical solutions can be found. I am trying to solve it by using function pdepe. Thanks again for your help! 2010-06-18 10:17:58
It seems like unsteady diffusion equation.
First, you should make sure wether it has the analytical solution(s).
You should know the qj exactly and then use numerical method, like finite volume method to solve them.
Sometimes, pdetool in matlab cannot solve too complex differential equations.
One of the methods is using fluent UDF.
