dsanthosh2 is on a distinguished road
I want to compute Richardson no Gr/Re^2 at each and every grid node. I am solving supercritical fluid flow. therefore the wide change of properties like density, viscosity..which increases the buoyancy force. So I have to find each and every cell the value of Gr/Re^2. Could any one help how to find Ri value using Fluent. Thanks in advance.
