FDM_C++

The repository contains codes that I wrote while practicing OOP. Following are the description along with some results of different files.

FDM.cpp

The code solves the ODE dn/dt=-an analytically and using Finite Difference Method (forward differencing). It also calculates the absolute error between the two. Following graph shows the values calculated by two methods.

FDMMethod.cpp

The code solves the ODE dn/dt=-an using central differencing, forward differencing and backward differencing methods.

1DHT.cpp

The code determines steady state temperature distribution in a fin as shown in below.

The code uses FDM with Drichelt and Neumann Boundary Conditions at the two ends. The below graph shows temperature distribution across the fin.

gauss_seidel.cpp

The code solves Ax=b using the gauss-seidel method.
