No setup in ANSYS is required after you plug in more RAM.

I can answer for Structural models. If the solver only needed 4 GB of ram to solve the model, then changing from 8GB to 16GB will have no effect on the solution time. If you are on the Student license, the solver will not solve large models, so you might not get to the point of needing more than 8GB.

If you are on a full license, look at the largest model you have. If you use the Direct solver, in the Solution Information folder, you can search the Solution Output for the Memory report. It will tell you how much RAM it needed to solve. If it solved incore, then you had enough RAM. If it had to solve out-of-core, then adding RAM will reduce the solve time.
