Firstly, an immiscible Cahn-Hilliard two-phase flow emulsified smooth particle hydrodynamics diffusion simulation method FCE-SPH is proposed to describe the mixing and emulsification decomposition process of sea oil spills by combining the fluctuating wind field. Secondly, an offset-attention based two-phase flow physical-aware graph attention network deep reinforcement learning network OTF-DRL is designed to accelerate fluid simulation. The offset heterogeneous graph attention module is used to enhance the represent ability of the network to obtain particle feature information. Under different working conditions, the physical process of crude oil leakage and diffusion and the oil weathering process are analyzed. The experimental results show that the proposed method can simulate the offshore oil spill diffusion phenomenon realistically. The calculation time for simulation of OTF-DRL is shortened by 49.63%.","PeriodicalId":159974,"journal":{"name":"Journal of Computer-Aided Design & Computer Graphics","volume":"37 7","pages":"1116-1127"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciengine.com/doi/pdf/6DFE9DFA569A45B0A4005646307A2F2B","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The virtual reality-based surgical simulation training can effectively improve the training effect and avoid surgical risks. For the characteristics of MICS-CABG, we propose a real-time simulation method of minimally invasive coronary artery bypass grafting operation based on XPBD framework. A tetrahedral exoskeleton model is used to realize the physical deformation of the heart, and a cylindrical geometry is used to represent the physical model of the surgical instrument. Based on the GPU-accelerated XPBD simulation framework, we established the Cosserat constraints based on XPBD, using the coronary artery mid-axis to achieve the coronary artery deformation simulation, and used tetrahedral volume constraints to achieve the heart deformation simulation. Furthermore, based on the collision detection between the surgical instrument and the physical model of the heart, non-embedding constraints and attachment constraints were introduced to generate the feedback force for the interaction between the tool and the soft tissue. The experimental results show that the proposed method has high simulation efficiency and stability in real-time interaction between the surgical instrument model and soft tissue model. In the simulation scenario containing 100 000 physical units, the simulation rate can reach 60frames/s. with the force feedback simulation frequency over 1 kHz, which can maintain a high-quality visual effect.","PeriodicalId":159974,"journal":{"name":"Journal of Computer-Aided Design & Computer Graphics","volume":"36 11","pages":"1842-1851"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciengine.com/doi/pdf/BFFEC3DBA74F42B990716AB2C9232F4F","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
