Hi,

I'm very new in the field of optimization. I have a very simple class project where one specie is coming out from one domain to another one (continuity BC between the domain and insulation at the outer domain. It is a pure diffusion process where the diffusivity in the inner domain is a function of time, D=D0*(1+a*t+b*t^2);
species diffusivity in the outer domain in Do.

My experimental values are like this:
Time (t,sec) Concentration (mol/m^3) in the inner domain
0 1
50 0.8
100 0.7
200 0.55
300 0.40
500 0.25

i want to optimize for D0,a,b. Could any please inform me how could i do that? Thanks in advance.

regards,
Ferdous
