csuperfect New Member Join Date: May 2010 Posts: 6 Rep Power: 15	Hi, everyone. Recently, I am working with DES. There are 2 problems that I would like to ask for help here. First, "very low mesh count for inlet velocity, have the levels of sub-grid viscosity been checked", the question is how can I check the levels of sub-grid viscosity in Fluent? Second, "high levels of sub-grid viscosity could account for the non-turbulent appearance in the wake of the blunt body", the question is what does the high levels of sub-grid viscosity mean? Any feedback is very welcome. Thanks!
