Three-Dimensional-Nozzle-Design-Code

This package contains 3 programs written for the Microsoft Visual C++ compiler:

1. 2D Method of Characteristics, MOC_GRID_BDE

   • Computes a planar or axisymmetric two-dimensional nozzle contour based on user inputs using method of characteristics

2. Streamline Tracing Tool, STT2001

   • Performs streamline tracing on a supplied nozzle solution grid (usually generated by MOC_GRID_BDE)

3. 3D Method of Characteristics Design Tool, 3D_MOC

   • Computes three-dimensional flowfield properties for a given 3D nozzle contour. This could be a modified version of a nozzle contour generated by MOC_GRID_BDE.

Each program is contained in a separate folder containing source code and sample outputs. These programs are designed to use the Microsoft Foundation Class (MFC) libraries to generate the GUI windows for user input.

Detailed descriptions of the mathematical basis and operation of each program are provided in the attached report:

three-dimensional-nozzle-design-code's Issues

Is mach number's calculate in KLThroat method right？

We known Kliegel and Levine's solution about 'Transonic Flow in Small Throat Radius Curvature Nozzles' is based on hall's work, in hall's paper, he uses the critical velocity of sound(a*) to normalize the axial and radial velocity components, why the code in KLThroat method calculates mach number is just use sqrt(U*U+V*V)?https://github.com/nasa/Three-Dimensional-Nozzle-Design-Code/blob/master/MOC_Grid_BDE/MOC_GridCalc_BDE.cpp#L3167

I have some problems with the use of this code

I downloaded the source code of this project and tried to debug the 2D MOC program. But I found that I couldn't find the main function anyway. I don't know about MFC. Can someone help me to solve this problem? How can I run the project code correctly?
