Hi all:
The solution to my problem requires solving 16 PDE's at once. This shouldn't be hard - but you'll know what my problem is in a minute. The 16 PDE's :
∂/∂t (I+i) + Kn*μi ∂/∂x (I+i) + I+i = I0
∂/∂t (I-i) + Kn*μi ∂/∂x (I-i) + I-i = I0
for i's ranging from 1 to 8.
That comes up to 16 PDE's.
My domain is x ∊ [0,1]
I have numerical values for all the coefficients except I0 .
Also I have Dirichlet Boundary Conditions for I+i at x=0 and I-i at x=1 (for all 8 of each of them)
The only problem that I do have, is that my source term I0 is to be defined as:
I0 = 0.5 * [ Σ wi.I+i + Σ wi.I-i ] (summations are for i=1 to 8)
I also know the values for wi . (which are different for each i)
How can I solve this problem with Comsol??
Any Suggestions?
Thank you.
