  1. 1. Analysis of Mutable Game Environments Built on a Tetrahedral Mesh : Tetras, a Potential Alternative to Voxels

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

    Author : Noah Tell; [2023]
    Keywords : Voxels; Tetrahedron; Tetrahedral Mesh; Tetrahedralization; Tessellation; Mutable Environment; Editable Terrain; Deformable Environment; Boolean Operations; Real-Time; Computer Games; Computational Geometry; Voxlar; Tetrahedror; Tetrahedralisering; Tessellering; Formbar Terräng; Booliska Operationer; Realtid; Datorspel; Beräkningsgeometri;

    Abstract : Historically 3D game environments have almost always been immutable. Mutable environments are a technical challenge that will affect performance. For games of the future to continue approaching realism, mutable environments are an essential step. 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. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

  5. 4. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Esbjörn Zachén; [2019]
    Keywords : Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Abstract : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  6. 5. Simmulating pullout forces in particleboard

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Tapiwanashe Phiri; Niklas Björkman; [2019]
    Keywords : transversely isotropic material; orthotropic material; particleboard; finite element analysis; material model;

    Abstract : Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. READ MORE
