When you first open it, the interface might seem a bit overwhelming. Fortunately, there are very well made videos and tutorials that explain in great detail how to make your first simulation. Again, if you don't mind others looking over your shoulder, 3000 hours per year of simulation are free. It's a lot, and doing what I do, I cannot imagine ever consuming them all.
For simulations to run quicker, we've designed the simplest possible one-piece headshell. You can find the document here
, and you're welcome to use it for your own experiments.
