Calculator : Composite Wall Conduction with Convection
Category   : Conduction

Files Included:
  - composite_wall_convection.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 -O3 composite_wall_convection.f90 -o composite_wall_convection_calc

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

  composite_wall_convection_calc < 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':
