Revision as of 16:24, 22 September 2005
When we shall fill this page, I offer to make common identifications, because in different issues was used different notation.
Also we beg everybody to help me with original works. Later I shall write, what is necessary. If anyone have literature connected with convective schemes, please drop me a line.
We shall be very glad and grateful to hear any critical suggestion (please drop a few lines at Wiki Forum)
It is just a skeleton, but we hope that it will be developed into the good thing

Dear friends
It's just a scrap. Later I'll correct it, although it's a complete working code

Sample code for solving Smith-Hutton test - Fortran 90
It's a results, obtained using this code (UDS and HLPA schemes)
Below it's cleary seen the numerical diffusion impact, comparing the contour fields obtaining using the UDS and HLPA. A bit later we shall place here a solution gained with QUICK scheme, and it will be seen the osscilations.
