BIg BIg Problems....SUPERSONIC FLOW OVER A FLAT PL
hi there, i'm edison from Malaysia. i'm facing the big problem now....i'm asking to develop the program. But the problem is i even cant get the finitedifference equation to write the source code in C++ language.... so i need ppl give help now.... the quetions i have is about the SUPERSONIC FLOW OVER A FLAT PLATE: NUMERICAL SOLUTION BY SOLVING THE COMPLETE NAVIERSTOKES EQUATIONS. i'm using the Maccromack method to solver this problems. the finitedifference eq. was so complicated... its include the secondorder of partial differeciation TAUyy,TAUxx,TAUyx..... so can u give me some guide??
below is the link to the questions. http://s6.yousendit.com/d.aspxid=39B...R2X0WJL5KG31MO thanks for help...i appreciate so much....

Hi,
Your file has expired. Anyway, your problem is a classical one, and is not considered a BIG BIG one ;) It corresponds to the chapter 10 of http://www.cfdonline.com/Books/show_book.php?book_id=3 Regards 
Re: BIg BIg Problems....SUPERSONIC FLOW OVER A FLA
thanks for rely Buch.... but i stil dono wat to do with the secondorder partial differenciation la... also i dono how to call function during writing the program... could u help me>? or any other have done the questions in Chapter10 before?? i wan the solution for the finite difference eq. so that can start write the programme..... thank alot

Re: BIg BIg Problems....SUPERSONIC FLOW OVER A FLA
Hi,
1) for the 2nd order differenciation, everything is explained before in the book. You can find some examples of codes on the web, especially simple ones to see how a discretized equation is coded, like in http://www.sali.freeservers.com/engi...cfd_codes.html 2) to call a function/subroutine etc. it depends on the language you are using. Try first to set up a very small program, to see how to call a function and to pass arguments from a function to another. 3) if you are waiting for "the solution ", you may wait for long, you'd better try first to do it by yourself, then try to ask your coursemate and/or teacher ... Good luck 
Re: BUch and other...can help me check??
i've try to derive the equation as below....(get in the link) http://s25.yousendit.com/d.aspxid=0Z...Q1UMHBUYIYRYV8 can u help me check is that correct? another question is .....is that we need to do the call fucntion for MIU and LANDA also?? thanks a lot hope u reply soon.....:)

Edison,
To be rather honest... those equations are no big deal to set up. Get hold of a good CFD book  eg. Anderson, as suggested by someone & go through the learning exercise. you will thank yourself in the end. You can even do a rough setup in Matlab. diaw...
