Just the other day I stumbled upon something while running a flow simulation that I never knew was there and thought I'd share it with you all. I frequently run flow simulation with the solver window opened up showing my goals. I like doing this because I can then see whether the goals of my simulation are converging like I would expect or not. If you're not familiar with a goal plot while running a flow simulation, this is what is looks like.
Well the other day I was watching my analysis progress and just happened to accidentally click my right mouse button while hovered over the graph portion of the goal plot, and to my surprise this dialog popped up!
With this dialog now I actually change how I'm able to view my goal plot. For example, if I'm running a time dependent study rather than a study state, maybe I want to look at how my goals are changing with respect to the physical time I sent my study up for rather than just the iterations which doesn't tell me much. With these options, I can just change my X-axis units to physical time rather than iterations and I'm good to go. There are lots of useful options in here, but the other one that I think I will use a lot is the field called Length Scale. There are often times where an analysis will run for a very long time and have many iterations. This often results in a goal plot graph that is very stretched out and it's hard to get a good picture of how the goals have converged because you have to scroll from left to right to get a good picture of this. With the Length Scale though, you can reduce that X-axis scale so that you're able to see a more zoomed out picture of your convergence plot.
I know this isn't anything earth shattering but hopefully it's a tid-bit that maybe you didn't know!
