This volume contains the abstracts presented at the 8th International Conference on Numerical Modelling in Engineering (NME 2025), held in Ghent, Belgium, from 29 to 31 July 2025.
The conference gathered international experts from academia and industry to discuss recent advances in numerical methods such as FEM, BEM, and IGA, and their application across a broad spectrum of engineering disciplines.
Special focus was placed on the industrial relevance of numerical simulations in fields including Civil, Aerospace, Mechanical, Materials, Biomedical, Electrical, and Electronics Engineering.

The Effect of Gust on Blended-Wing-Body Civil Aircraft Chenfang Cai 1, Jianghao Wu 2, a and Bin Liang 1 1 China Academy of Aerospace Aerodynamics, Beijing, PR China 2 School of Transportation Science and Engineering, Beihang University, Beijing, PR China a buaawjh@buaa.edu.cn Keywords: blended-wing-body; gust; computational fluid dynamics; aerodynamics; dynamic response Abstract.
In this paper, aerodynamic properties of Blended Wing Body (BWB) civil aircraft are studied by two models: one calls complete model that is computed by numerical simulation coupling equations of motion with the Navier-Stokes equations, and the other doesn’t consider the equations of motion (without dynamic response).
As a civil aircraft, the economy is not as important as the safety, according to FAR25.341 [6], when cruising, the gust load should be count to ensure the safety of the aircraft and sometimes the economy makes a concession for safety when designing an aircraft.
Model and method The BWB model used in this paper is a 250 passengers BWB civil aircraft [11], the definition of frames sees Fig.1, let (x’, y, z’) be the body fixed reference frame with the original fixed in the center of gravity, and (x, y, z ) be the air reference frame.

The finite element model is established to simulate the actual structure by Midas Civil.

Checking Computation for Bracket Structure of Jinqinggang Bridge Shiming Liu1 a, Hui Zhao2 b and Zulin Yang2 c 1 North China Institute of Water Conservancy and Hydroelectric Power, Zhengzhou, China 2 The Second Design and Research Institute of Water Conservancy and Hydroelectric Power of Hebei Province, Shijiazhuang, China asokd_0@163.com, b418058127@qq.com, cyangzhulin@126.com Keywords: bridge engineering; prestressed concrete box girder; bracket structure; checking computation; probabilistic limit state.
According to the design drawings of bracket structure of the Jinqinggang bridge and the actual load case, the analytical model is founded by the finite element analysis software MIDAS/CIVIL.
Wang et al [3] use the software MIDAS/CIVIL, and study the stress and deformation of the bracket in the standard load, and point out the precautions during the construction.
According to the structure materials, sizes, loads and boundary conditions, the paper makes use of the software MIDAS/CIVIL, and establishes the three-dimensional finite element model which has a total of 1280 nodes, 2195 elements.
