[SOLVED] Solving PDE
I am just wondering, is there any gerneral method in solving PDE's or just by guess works??
thanks...

Is there a general method of solving them??
There are three main types of PDEs: elliptic, parabolic, and hyperbolic. Elliptic PDEs involve steady-state problems, parabolic PDEs involve transient problems, and hyperbolic PDEs involve wave-like problems. To determine the type, you need to analyze the coefficients and boundary conditions of the PDE.
Some common techniques for solving PDEs include separation of variables, method of characteristics, finite difference methods, finite element methods, and Fourier or Laplace transforms. The choice of technique depends on the type of PDE and the problem at hand.
Yes, some PDEs can be solved analytically using techniques such as separation of variables, but this is only possible for simple PDEs with specific boundary conditions. In most cases, numerical methods are used to approximate the solution.
To check the accuracy of a solution for a PDE, you can compare it to known analytical solutions, if available. You can also vary the step size in numerical methods and observe the change in the solution. Additionally, you can use error analysis techniques to determine the accuracy of the solution.
There are many software packages available for solving PDEs, such as MATLAB, Mathematica, and COMSOL. These software have built-in functions and tools for solving various types of PDEs. It is important to choose the software that best suits your problem and your level of expertise.
