Operational heliospheric space weather models require simulations of coronal mass ejections (CMEs) much faster than real-time for all observed events. Currently, this cannot be routinely achieved by simulations that involve the origin of the CMEs. Thus their white-light appearance in coronagraphs is used to fit the geometric and kinematic parameters and launch simple, CME-like structures into the background solar wind. Propagation and interaction in the heliosphere are then solved by a 3-D magnetohydrodynamic (MHD) code. We use the “cone” hydrodynamic model for all observed CMEs and the “spheromak” magnetohydrodynamic model for selected well-observed CME events. Background solar wind is calculated using the daily-updated WSA (Wang-Sheeley-Arge) coronal maps. Heliospheric computations are realized by the 3D MHD code ENLIL. We are making continuous simulations of the heliospheric space weather up to 2 AU. We present numerical results to provide the global context of solar wind stream structure and CMEs from August 2018 up to the present. This period involves the Parker Solar Probe, BepiColombo, and Solar Orbiter missions. We compare numerical results with remote white-light observations and with in-situ measurements of plasma parameters for selected events of interest.
