The launches of Parker Solar Probe (Parker) and Solar Orbiter (SolO) are enabling a new era of solar wind
studies that track the solar wind from its origin at the photosphere, through the corona, to multiple
vantage points in the inner heliosphere. We perform steady-state, data-driven magnetohydrodynamic
simulations of the solar wind with the GAMERA model and compare the model results with various sources of in-situ measurements. Using the ADAPT and AFT flux transport models as inputs, we derive boundary conditions for the model using a self-contained implementation of a potential field source surface extrapolation, a Wang-Sheeley-Arge relationship between field line properties and solar wind speed, and a simplified Schatten current sheet model. We focus on Carrington rotation 2258, which overlapped with most of Parker Encounter 12 from 2022 May 27 to 2022 June 7. Despite the relative simplicity of the models, we find generally good agreement between the simulation results and the observed values of the solar wind magnetic field, density, and radial velocity at Parker, SolO, and Earth.
Furthermore, we find that we can trace field lines from Parker to an outflow region observed by Hinode/EIS at the solar surface.
