artifical compressilblity method for incompressibl
 

Dear friends: I have some questions abou the artificial compressibility method for the steady incompressble flow. since the ACM add an unsteay term in the continuity equation. but i want solve a steady problem. so how to implement this method. would you please give me some detai about it. regards

For steady problems, the time is a fictitious term and you march in time until the solution has converged. Look for papers by Kwak ( you may find it in NASA repositories too).

Thank you very much for your feedback. Could you please give me the website of NASA repositories regards

Dear ztdep,

Using the 'Penalty Method' is a nice, simple way to perform 'almost-incompressible' fluid flow calculations - marching forwards in time.

Take a look at the <www.freefem.org> site I mentioned in another message, or try the site <www.adthermtech.com/wordpress3> for some papers mentioning use of this method.
