Simulation Performance

What the simulation costs to run, and what it gives up when it is made cheaper. Two settings account for nearly all of it — the mesh resolution and the number of steps — and they bottleneck independently, so making a run faster starts with knowing which of the two is currently in the way.

Ordered from the machine doing the work to the setting chosen before the run starts.

• CPU Usage During Simulation — Why a run is slow while the CPU is not saturated: single-threaded geometry removal against multi-threaded physics, and the two independent cost drivers
• Mesh Resolution — Choosing a mesh width: what it costs in run time, how little it moves the physics, and the one kind of geometry it can make disappear
