Calculator : Transient Conduction — 1D Series
Category   : Conduction

Files Included:
  - transient_conduction_1d.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 transient_conduction_1d.f90 -o transient_1d

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

  transient_1d < input.txt

-------------------------------------------------------------------------
3. Input File Details
