Calculator : Semi-Infinite Solid Conduction
Category   : Conduction

Files Included:
  - semi_infinite_solid.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 semi_infinite_solid.f90 -o semi_infinite_calc

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

  semi_infinite_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':

  Line 1 (Boundary condition type (1=Constant Temp, 2=Constant Heat Flux, 3=Convection)
): 1
  Line 2 (Initial temperature Ti [Â°C]
): 20.0
  Line 3 (Boundary parameter (Ts [Â°C] or qs [W/m2] or h [W/m2-K])
): 100.0
  Line 4 (Boundary fluid temperature [Â°C]
): 0.0
  Line 5 (Thermal conductivity k [W/m-K]
