Solar eruptions, such as flares and coronal mass ejections, are the major drivers of space weather between the Sun and the planets. Therefore, understanding the mechanism of solar eruption and further predicting solar eruption is an important prerequisite for the accurate and quantitative forecast of space weather. Although it has been well recognized that solar eruptions originate from the complex structure and evolution of the coronal magnetic field, the underlying physical mechanisms remain elusive. The key to studying the coronal magnetic field associated with solar eruption is to obtain the three-dimensional (3D) coronal magnetic field. Due to the difficulty of directly measuring the solar coronal magnetic field, physical models with numerical implementation and constrained by the photospheric magnetogram have been developed. The model statically reconstructs the three-dimensional coronal magnetic field with a single magnetogram snapshot and dynamically simulates the coronal magnetic field with a time se
