myty New Member Join Date: Oct 2011 Posts: 19 Rep Power: 14	I am new to ANSYS/FLUENT and trying to simulate rayleigh-benard convection. I just have some confusion or may be i do not understand how to work with FLUENT. i am trying to simulate rayleigh-benard convection but i am seeing cell formation even without applying any instability after critical Ra = 1708. Could anyone answer me why it is happening in FLUENT. Thanks in advance
