code to solve second order coupled PDE

[Abderrahim. B]

Hi!

Refer to this documentation page.

https://www.mathworks.com/help/matlab/math/partial-differential-equations.html

Hope this helps

can you write the direct code to write the equation

i am not getting the solution for the given equation

Answer 1

[Torsten]

It's not a system of PDEs, but of ODEs.

Convert the two second-order ODEs to a first-order system of 4 ODEs. Then use ODE45 to solve if the boundary conditions are all given in one point and BVP4C if the boundary conditions are given in two or more different points.

any related examples for the problem

[Torsten]

What are the boundary conditions ? You need 4.

The first example "Solve Second Order BVP" under

https://de.mathworks.com/help/matlab/ref/bvp4c.html

should show you how to proceed.

The problem seems very similar to a question you already asked in this forum:
