COCONUT: Toward practical time-evolving Sun-to-Earth magnetohydrodynamic modeling

Haopeng Wang, Stefaan Poedts, Andrea Lani +16

Due to computational efficiency and numerical stability limitations, coronal simulations constrained by static magnetograms are typically performed first and then used to drive inn…

MHD modeling of magnetic flux evolution around solar maximum by the coronal model COCONUT

Haopeng Wang, Stefaan Poedts, Andrea Lani +15

In this paper, we simulate the magnetic flux evolution at different heliocentric distances during two solar-maximum Carrington rotations (CRs) using the time-evolving coronal magne…

Efficient magnetohydrodynamic modelling of the time-evolving corona by COCONUT

Haopeng Wang, Stefaan Poedts, Andrea Lani +6

Compared to quasi-steady-state corona models that are constrained by a time-invariant magnetogram over a CR period, time-evolving corona models driven by time-varying photospheric…

SIP-IFVM: Efficient time-accurate magnetohydrodynamic model of the corona and coronal mass ejections

H. P. Wang, J. H. Guo, L. P. Yang +7

In this paper, we present an efficient and time-accurate three-dimensional (3D) single-fluid MHD solar coronal model and employ it to simulate CME evolution and propagation. Based…

Constraining the inner boundaries of COCONUT through plasma \b{eta} and Alfvén speed

Michaela Brchnelova, Boris Gudiksen, Mats Carlsson +2

Space weather modelling has been gaining importance due to our increasing dependency on technology sensitive to space weather effects, such as satellite services, air traffic and p…

CME propagation in the dynamically coupled space weather tool: COCONUT + EUHFORIA

L. Linan, T. Baratashvili, A. Lani +4

This paper aims to present the time-dependent coupling between the coronal model COolfluid COroNal UnsTructured (COCONUT) and the heliospheric forecasting tool EUHFORIA. We perform…
