I want to solve the following coupled PDEs with Comsol.
My equations:
1) dA/dx=0.1*(dA^2/dx^2+dA^2/dy^2)-0.01*A*B*exp(-6/C)
2) dB/dx=0.1*(dB^2/dx^2+dB^2/dy^2)-0.001*A*B*exp(-6/C)
3) dC/dx=0.1*(dC^2/dx^2+dC^2/dy^2)+0.001*A*B*exp(-6/C)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
and the boundary conditions:
1) A-0.1*dA/dx=0
2) A-0.1*dA/dx=3;
3) B-0.1*dB/dx=1;
4) B-0.1*dB/dx=0;
5) C-0.1*dC/dx=0;
6) dC/dx=0;
7) dA/dy=0;
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
with d/dx--- I mean partial derivative
How could I implement this?
Which PDE?
Thanks a lot,
