Calculator : Compressible Flow
Category   : Fluid

Files Included:
  - compressible_flow.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 compressible_flow.f90 -o comp_flow

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

  comp_flow < 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 (Solver mode (1=Isentropic Relations, 2=Normal Shock Relations)
): 1
  Line 2 (Inlet Mach Number
): 1.5
  Line 3 (Specific Heat Ratio (gamma)
): 1.4
  Line 4 (Stagnation Temperature [K]
): 300.0
  Line 5 (Stagnation Pressure [kPa]): 101.325
