  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    University essay from KTH/Teknisk mekanik

    Author : Ziyi Liu; [2024]
    Keywords : Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Abstract : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. READ MORE

  3. 2. Real-time Soft Body Simulation using Extended Position-Based Dynamics and Tetrahedral Deformation

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : William Kamnert; [2023]
    Keywords : Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

    Abstract : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. READ MORE

  4. 3. Optimizing Realistic 3D Facial Models for VR Avatars through Mesh Simplification

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Beiqian Liu; [2023]
    Keywords : Mesh Simplification; Virtual Reality; Realistic Avatars; 3D Face Reconstruction;

    Abstract : The use of realistic 3D avatars in Virtual Reality (VR) has gained significant traction in applications such as telecommunication and gaming, offering immersive experiences and face-to-face interactions. However, standalone VR devices often face limitations in computational resources and real-time rendering requirements, necessitating the optimization of 3D models through mesh simplification to enhance performance and ensure a smooth user experience.

  5. 4. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Georgios Nentidis; [2023]
    Keywords : ;

    Abstract : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

  6. 5. A performance comparison between quadtree and tessellation LOD solutions for planetary terrain

    University essay from Blekinge Tekniska Högskola

    Author : Julius Wendt; [2023]
    Keywords : level of detail; planetary; rendering; quadtree; tessellation;

    Abstract : Background. Rendering planets with high detail from orbit to surface level is becoming increasingly common in video games. In this thesis, two solutions to achieving this will be compared, a quadtree solution and a tessellation solution. These solutions both implement an adaptive level of detail on a spherical shape.
