PDEs

1. PDEs Solver(Partial Differential Equations Solver)

The coverage of these problems is:

• Wave equation using Finite-Difference method. ## $\frac{\partial^2 U(x,t)}{\partial t^2}=c^2\frac{\partial^2 U(x,t)}{\partial x^2}$ ##

• Heat equation using Forward-Difference method. ## $\frac{\partial U(x,t)}{\partial t}=c^2\frac{\partial^2 U(x,t)}{\partial x^2}$ ##

• Laplace's equation using Dirichlet method. ## $\frac{\partial^2 U(x,y)}{\partial x^2}+\frac{\partial^2 U(x,y)}{\partial y^2}=0$ ##

• Poisson's equation using Finite-Difference method. ## $\frac{\partial^2 U(x,y)}{\partial x^2}+\frac{\partial^2 U(x,y)}{\partial y^2}=F(x,y)$ ## This app build in Visual Studio 2017 CE.
  Use libraries :

• mXparser(free version/NON-COMMERCIAL USE) by Mariusz Gromada as math expression parser.
• ProEssentials Gigasoft(free version/evaluating) for Viewing graph 3D.

3. Wave Equation py

Wave equation using Finite-Difference method. ## $\frac{\partial^2 U(x,t)}{\partial t^2}=c^2\frac{\partial^2 U(x,t)}{\partial x^2}$ ##
This app build in PyCharm 2022 CE.
Use lib:

1. pymep as math parser to input math equation at runtime.
   
2. plotly as 3D(Surface) graph to display on browser.
