CFD by anderson, chp 10.... supersonic flow over flat plate

varunjain89 · March 25, 2010, 07:22

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.
