And also my domain is part of whole domain which repeats. so I gave periodic boundary instead of mass flow inlet. Thanks Ravi Duggirala

Faces ABFE , EFGH, HGDC, ABCD are symmetric boundary condition. Actually I ran few cases with AEHD and BFGC as periodic BC (no wall in that case) and got expected results... My next step is to consider those walls and i am not able to succeed in that... yeah i am from andhra... basically from Vizag. did B.Tech at GITAM. Waht abt u... thanks Ravi
