Asymmetric flow code

sandip

Hi,

I am developing the code for steady state fully developed 1d flow across a asymmetric duct ,one side being rough. I am facing following problems: 1. first of all when I am running the code for the symmetric case in which case both the wall are smooth I am not getting the symmetric variation of velocity.I am travelling from node on one wall to the other Is this the reason for descrepancy??DO I need to travel from both wall simultaneously and merge at the mid of the duct,If this is case then how to do the same for asyymetric flow which i have discussed above. Moreover the scheme which I have used for discreatising the modified RANS is straight forward.

Desperatly looking for help. Thanks Sandip
