What is the difference between fluid flow (fluent) at " analysis system " and fluent at "component system" in ANSYS 18.2

I am new at using ANSYS, now I am still do some practice from the ANSYS tutorial, one workshop starts with fluid flow (fluent) at " analysis system " tree, and the other one starts with fluent at "component system" tree. If my main work at fluid field, what is the most appropriate ?

There is no difference in the Fluent code. The only difference if the starting point of your analysis. If you have a mesh already, you can directly import it in the Fluent from the component tree while if you have to design your geometry, mesh it and then transfer it to Fluent, you should use the Fluent from the analysis tree. Attached is a screenshot which might explain this better.

So, Fluent from the analysis tree has 5 sub-components: Geometry, Mesh, Setup, Solution, and Results. So you build your geometry, mesh it, set up the relevant physics, solve it using Fluent and post-process the results.

Some of the Fluent tutorials focus on the setting up the physics and solving it which is why they provide you a meshed geometry, to begin with, and concentrate more on the setting it up aspect.

Thanks a bunch Raul.
