Yes, I have done the normal diffusion problem numerically, and I have the code, but I think you're looking to solve it yourself, right? Read up on NDSolve for partial differential equations in the Mathematica documentation. ________________________________________ From: Brampftl [alexandre.abreu at physik.uni-augsburg.de] Sent: Thursday, August 18, 2011 03:22 To: mathgroup at smc.vnet.net Subject: [mg120973] Parameter optimizatrion in modified diffusion equation Hello! I am new to Mathematica and am trying to figure out if it can solve my problem: I have a modified Diffusion equation: dc/dt == D d^2c/dx^2 - r c exp(-n t) c: concentration D: Diffusion constant r: reaction rate n: time constant What i need to do is to solve the equation and find a set of parameters to fit my experimental results. Has anybody an idea if that's possible in mathematica and if so how to implement it? Thanks! Alex
