1. 1. Simulation of a multi phase flow in a rotating-lid driven cylinder

   University essay from Institutionen för fysik

   Author : Mats Johansson; [2013]
   Keywords : Navier-Stokes; Cahn-Hilliard; Flow; Cylinder; Multi Phase;

   Abstract : This report describes the development of a software for computing viscous incompressiblemultiphase ows. The software does this with solving the coupled non-linear Navier-Stokes(Fluid) and the Cahn-Hilliard (Phase-Field) equations using a Finite Element Method. READ MORE

3. 2. Development of a Parallel Finite-element Tool for Dynamic Soil-structure Interaction : A Preliminary Case Study on the Dynamic Stiffness of a Vertical Pile

   University essay from KTH/Bro- och stålbyggnad

   Author : Mårten Ullberg; [2012]
   Keywords : dynamic stiffness and damping; finite-element analysis; steady-state analysis; parallel calculations; PETSc; piles; pile-groups;

   Abstract : This thesis has two major goals; first to develop scalable scripts for steady-state analysis, then to perform a case study on the dynamic properties of a vertical pile. The scripts are based on the numerical library PETSc for parallel linear algebra. This opens up the opportunity to use the scripts to solve large-scale models on supercomputers. READ MORE

4. 3. Implementing a Component Based Parallel Distributed Finite Element Solver

   University essay from Lunds universitet/Teknisk fysik (CI); Lunds universitet/Byggnadsmekanik

   Author : Fredrik Hansson; Filip Johansson; [2008]
   Keywords : Technology and Engineering;

   Abstract : Parallel computing is becoming more and more important in modern Finite Element Software. As problems grow larger, computation on a single processor may not be fast enough. To overcome this problem, one can utilize parallel programming using e.g SMP-machines or clusters. READ MORE
