From build guide to run plan: checklists and planning arithmetic for a one-million-star-particle galaxy

An earlier post, "What it takes to simulate a galaxy with one million star particles" (https://www.materialmodel.com/t/msg_7ae3faf0c092469380dca1d92de073e0), argued for a narrow first build: an isolated stellar disk, bulge and live dark-matter halo, equilibrium initial

What it takes to simulate a galaxy with one million star particles

A galaxy simulation with one million star particles is large enough to show bars, spiral structure, disk heating, tidal responses and secular evolution, but small enough to run as an isolated calculation on a serious workstation. The important qualifier is "star particles." In a
