Calculator : Rectangular Fin Performance Solver
Category   : Conduction

Files Included:
  - rectangulaire_Fin_heat_conduction.f90 (Fortran Source Code)
  - input.txt (Pre-configured Sample Input)

-------------------------------------------------------------------------
1. How to Compile
-------------------------------------------------------------------------
Make sure you have a Fortran compiler installed (like gfortran).
Run the following compilation command in your terminal:

  gfortran -ffree-line-length-none rectangulaire_Fin_heat_conduction.f90 -o rectangulaire_fin

-------------------------------------------------------------------------
2. How to Execute
-------------------------------------------------------------------------
Run the compiled binary and redirect the input.txt file into stdin:

  rectangulaire_fin < input.txt

-------------------------------------------------------------------------
3. Input File Details
-------------------------------------------------------------------------
The input file 'input.txt' contains sequential parameters separated by
newlines. Here is the structure of the included 'input.txt':

  Line 1 (Fin Length ($L$) [m]): 0.05
  Line 2 (Fin Thickness ($t$) [m]): 0.002
  Line 3 (Fin Width ($w$) [m]): 0.1
  Line 4 (Thermal Conductivity ($k$) [W/m-K]): 200.0
  Line 5 (Convection Coefficient ($h$) [W/m²-K]): 25.0
  Line 6 (Base Temperature ($T_0$) [°C]): 120.0
  Line 7 (Ambient Temperature ($T_\infty$) [°C]): 20.0
