With the development of computing science, digital simulation technology has been widely applied in the field of education. In university physics experiment teaching, software simulations can more intuitively display experimental phenomena and simulate laws, obtaining physical quantities that cannot be measured experimentally, thereby expanding the breadth and depth of experimental teaching. This paper uses COMSOL Multiphysics software to simulate and analyze the viscosity measurement experiment using the falling ball method. It studies phenomena such as the velocity field, pressure gradient, velocity changes, and force diagrams in the viscosity measurement experiment. The research found that COMSOL software provides high accuracy in experimental modeling, effectively assisting experimental teaching and development. This helps students deepen their understanding of the laws of physics experiments, cultivate their digital application skills, and ultimately enhance the effectiveness of experimental teaching.

Modern physics experiments, involving famous experiments and commonly used methods in the development of modern physics, are rich in physical ideas and scientific exploration value, playing an important role in physics education. Restricted by particularity of experimental instruments and operations, some modern physics experiments mainly focus on confirmatory experiments, lacking further specialized research. Taking X-ray crystal diffraction as an example, this paper preliminarily explores the integration of computer simulation into modern physics experiments, empowering experimental teaching with digital technology, enriching and updating the content of experimental teaching, stimulating students' interest in scientific research, and providing references for the reform and innovation of modern physics experimental teaching models.

Modern Physics Experiment is a compulsory course for students majoring in physics. Combining the characteristics of the course, introducing cutting-edge scientific research ideas and methods into teaching practice is one of the important directions of experimental course reform. This paper introduces the design of computational simulation experiments in modern physics experiments at our school. All the physical modeling and simulation contents are developed based on traditional photoelectric effect experiments. By studying the structures and properties of photocathode materials, the connotation and depth of basic experiments can be enhanced. This also improves students􀆳 understanding and mastery of relevant physical concepts, computational simulation processes and methods, increases their capacity for scientific and technological innovation, enhances their ability to fully apply knowledge, and provides some guidelines for the reform of university experimental courses.
