yogesh@cfd is on a distinguished road
hi
i am working with fluent and gambit software. i am modelling flow in cyclic wind tunnel.
i have made 3 d geometry of cyclic wind tunnel with hexagonal cross section and meshed successfully.
i am running the exported file of gambit in fluent with boundary condition as velocity inlet and pressure outlet in order to find out pressure drop in wind tunnel, breaking wind tunnel at one place where we are going to place fan and making inlet and outlet at that place.
but now after putting boundary conditions solution is converging but at the end message is coming like " reverse flow at 6 faces" even solution is converged
i have attached the grid of the wind tunnel model with this and the portion with some gap at right top of the grid, at that position left face is the inlet and right face is outlet
thank you
in advance
regards
yogesh
