# Orr Sommerfeld equation

• URIA
In summary, to solve the Orr–Sommerfeld equation for plane Couette flow using numerical methods, you can use a finite difference method and an iterative approach such as the Gauss–Seidel method. References for this approach can be found in the literature, such as the ones listed above.

Ra'ananYou can try using a finite difference method to solve the Orr–Sommerfeld equation. You can start by discretizing the equation with the central difference scheme and then use an iterative approach such as the Gauss–Seidel method to solve the resulting system of equations. This approach has been used in the past to solve this type of equation numerically. You can find more information about this in the following references:1. F.
