	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.

	The European XFEL provides femtosecond X-ray pulses with a MHz repetition rate in an extended photon energy range from 0.3 to 30 keV. Soft X-rays between 0.3 and 3 keV are produced in the SASE3 undulator system, enabling both spectroscopy and coherent diffraction imaging of atoms, molecules, clusters, ions and solids. The high repetition rate opens the possibility to perform femtosecond time-resolved photoelectron spectroscopy (TR-XPES) on solids. This technique allows the simultaneous understanding of the evolution of the electronic, chemical and atomic structure of solids upon an ultrafast excitation. The realization with soft X-rays requires the use of MHz FELs. In this contribution, we present the mechanical design and experimental realization of the SXP instrument. The main technical developments of the instrument components and the TR-XPES experimental setup are described.
