  2. 1. Advancing Front Mesh Generation Techniques with Application to the Finite Element Method

    Author : Jan Frykestig; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advancing front method; mesh size distribution; automatic mesh generation; finite element method; surface mesh generation; spatial data structures;

    Abstract : The present study deals with automatic mesh generation with application to finite element methods. We focus our interest on unstructured mesh generation, and in particular on advancing front methods for which algorithms for meshing of two and three dimensional domains as well as of free-form surfaces are devised.

  4. 2. A Linearized Euler Method for Unsteady Flow in Axial-Flow Turbomachines

    Author : J. Pieter Groth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A linear Euler method for analysing unsteady inviscid compressible quasi three- dimensional flows in oscillating cascades is developed. It is applicable to both blade flutter and forced response problems. READ MORE

  5. 3. Procedures in Adaptive Finite Element Analysis

    Author : Peter Möller; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present work is concerned with topics related to some adaptive methods for the approximate solution of differential equations. Emphasis is on the finite element method for second order elliptic equations, where we use either p-refinement or remeshing with an advancing front mesh generator in order to improve approximate solutions.

  6. 4. Acceleration of Compressible Flow Simulations with Edge Using  Implicit Time Stepping

    Author : Evelyn Otero; Arthur Rizzi; Richard P. Dwight; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible CFD; Convergence Acceleration; Implicit Time-Stepping; LU-SGS; Upwind Type Dissipation; Line-implicit; Ordering; Parallelization; Parameters; Multigrid;

    Abstract : Computational fluid dynamics (CFD) is a significant tool routinely used indesign and optimization in aerospace industry. Often cases with unsteadyflows must be computed, and the long compute times of standard methods hasmotivated the present work on new implicit methods to replace the standardexplicit schemes.

  7. 5. Properties and Applications of Shear-Driven Lipid Bilayers

    Author : Peter Jönsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photobleaching; cell membrane; simulations; fluorescence microscopy; microfluidics; diffusivity; membrane proteins; lipid bilayer; mobility; model systems;

    Abstract : A supported lipid bilayer (SLB) is a lipid bilayer formed on a solid substrate. This system is currently one of the most common model systems used to imitate the properties of the cell membrane that surrounds human cells. READ MORE
