	At European XFEL, computational techniques such as FEA and CFD are widely applied in various scientific and engineering fields. In this contribution, a selection of multi-physics and multi-scaled models using FEA tools are presented, which virtually replicate the interaction process of XFEL beam with different materials, taking into consideration heat transfer, structural deformation and phase transition. To gain comprehensive insights into the fluid behaviors and performance of the detector cooling system and liquid sample delivery system, parametric studies are conducted using CFD simulation code FLUENT. Furthermore, a realistic simulation requires a secured process of Verification and Validation of the computational model. Specific guides and standards need to be followed to ensure the credibility and accuracy of the simulation results. Additionally, the FAIR principle for simulation data analysis is introduced at European XFEL. Based on reliable simulation data and real-time sensing data, the concept of digital twin will be integrated into the simulation framework, serving as a new safety constraint for monitoring and optimizing of the facility operation.

THPPP020	The Pre-alignment of High Energy Photon Source Storage Ring	alignment, target, laser, storage-ring	310
	S. Lu, L. Dong, L.L. Men, X.L. Wang IHEP, Beijing, People’s Republic of China J. Liang, T. Wang DNSC, Dongguan, People’s Republic of China
	In order to achieve 10 micrometer pre-alignment accuracy of storage ring in transverse and vertical, four laser trackers were used for set up a four-station multilateration measurement system. Experiment results show that the relative displacement measurement accuracy is better than 3 micrometer in 3-meter workpiece range, which can satisfy the real-time position feedback accuracy of the magnets in the process of ultra-high-precision pre-alignment. After two years of research and development, three pre-alignment standard workstations have been established. And the laser multilateration measurement method is adopted to the pre-alignment of the three, five and eight magnet girders in the storage ring of HEPS. Currently, 240 out of 288 girders have been pre-aligned after half a year of work.
