Dear Foamers,

I would like to integrate a variable (say A(x)), where x is the axial direction, varying from 0 to L (L is the length of the domain) and add it in the following PDE,

d^2T/dx^2 - integral(A(x) dx)(from 0 to L)*dT/dx + C = 0;

A(x) is obtained by solving another PDE.

Please let me know how to implement this.

Thanks

Vishal
