I’m currently using the following code to try and determine nozzle designs; https://www.mathworks.com/help/aerotbx/ug/solving-for-the-exit-flow-of-a-supersonic-nozzle.html. Whenever I run the provided code from MatLab I get the following error;
‘plotExpansionSchematic’ is used in Solving for the Exit Flow of a Supersonic Nozzle.
Error in project413fluidflow (line 4)
upperNozzle = plotExpansionSchematic(‘uppernozzle’);
I’ve tried looking through the .m file that is provided that uses the plotExpansionSchematic function but I honestly don’t know what I’m looking for to fix this error and get the code working and plots to show up, I haven’t chnaged anything about the code except the initial conditions whihc I am using the following conditions; exitMach=1.25, exitPres=421.512, and backPres=154.2166. Any help in resolving this error would be greatly appreciated. I will also note that when I run the code that defines plotExpansionSchematic I also get an error, in case that is part of the issue I’m having the error is:
>> plotExpansionSchematic
Not enough input arguments.
