The concept of nonlinear integrable optics is an exciting possibility for advancing the intensity frontier by suppressing parametric instabilities in high-intensity hadron rings. The integrable optics test accelerator (IOTA) under construction at Fermilab will provide the first experimental test of this concept, using nonrelativistic protons in a small ring, with a novel highly-nonlinear magnet. We present Synergia and Warp simulations of IOTA to explore the effects of space charge, chromaticity, and sextupoles used for chromaticity correction. The idealized zero-current dynamics is constrained by two integrals of the motion, but these real world physical effects pose serious challenges to the integrability. Hamiltonian perturbation theory is used to guide and better understand the simulations. In order to maximize community contributions to this important topic, we plan to share our Synergia and Warp capabilities through a public Jupyter (formerly IPython) service, which will be demonstrated.
