hi all

i'm trying to write C code for supersonic flow over flat plate. i'm reffereing CFD by JD anderson chp 10. i have a few doubts hope u can help.

firstly when i'm calculating vector E at plate surface and vector F at inflow, what should be the values of txy, txx, tyy, qx and qy, should i consider. should i take all of them to be zero...???

and after prdictor step, when calculating txy, then in one of the terms we need to calculate central difference, so our expression is something like....
U(i+1,j)-U(i-1,j) but we dont have values for U(i+1,j) at time step t+dt, right...??? so am i suppose to use the values calculated at previous time step.... coz that is the only way... jz needed to confirm..

thanks once again

Hi,

Sorry for the late reply.

I am posting the full code in the attachment, in C. All functions are named as in Anderson. Takes 70 seconds. No input files. All parameters are defined in preprocessor part..

Has been verified using the temperature profile at the trailing edge. Hope this helps.

Enjoy.

Ooops. Didn't upload.
Here should be the code.

there is one little error in the code, see attached pic.

The second Redx should be Redy.

Hi Cean,
Thanks for pointing out the error! I don know how the plots came out fine after the mess up . Thanks again

Mr.Balaji ,

I tried compiling the code u gave without making any change in it .

I just gave me errors . if possible take a look at this

Hi,

Please google on "Linking math library while compiling c++ codes" .

You basically add -lm option to your compile line so that the GCC can find power and absolute functions that are used in the code.

PS: I had the same error few years ago

Hope it helps

[Bajji]

Hi,

The code is already posted here! Just run the main.c.

IT worked Mr.Balaji . How do i obtain the plots ? . Do i need to use any other software to plot ? .

Thanks in advance

[Bajji]

Hi ,

Glad it helped you. You can use gnuplot for plotting results. A very small script will let you automate the plotting wonderfully. Its highly recommended for 2D plots.

Quick way to get things done is to copy the pressure and temperature matrices into Matlab and do surface plots. This is how I did it long back.

enjoy!

Thank you Mr.Balaji .

I got the u_profile via gnuplot . I myself tried writing the entire thing in matlab . it did gave me results after 15000 iterations . But the results are slightly over predicted . Can you help me with this ? I am not a good programmer .

Hi, I made one exe file under win7@32. It outputs some plots while simulating. You can press D,T,P,V,R key to switch between Desity,Temperature,Presssure, Vector and residual plot. At the end, it also outputs GMSH's pos files. You could view it with GMSH.

You could download it from here:

I encountered the following error~~~

Could you point out what is the problem?
I use visual studio 2010 to compile it
