unsteady species transport -- CFD Online Discussion Forums

solomon Guest Posts: n/a	I am simulating unsteady(pulsatile) laminar flow with species transport in a tube. I am implementing segregated solver with species transport selected in Fluent 6.1. The problem I encountered is the species profile in the flow domain at different time steps I found them zero even if at inlet there is a well defined non zero species concentration. The same problem for steady state case gives a reasonable result. I wonder if there is some procedure missed in the unsteady simulation.
