Urgent PDE Problem (Partial Differential Equation)

Hello, I have a partial differential equation attached.

The variable dependent coefficients: A(x,y), B(x,y), C(x,y), D(x,y) are known values, as well as Q_o.

I am trying to find the solution for the k variable.

Anyone have any idea on how to approach this?

Thank you very much!

Answer 1

[Torsten]

What are your boundary conditions ?

How do the coefficient functions A,B,C,D exactly look like ?

Two possibilities to solve:

- Method of characteristics

- Solve for dk/dx (e.g.), discretize dk/dy and solve the resulting system of ordinary differential equations using ODE15s, e.g. (Method of lines)

Best wishes

Torsten.

X[dy/DX+1] =y-1

? I am not sure if that is intended to be a question or a solution ?
