1. 1. Asynchronous Divergence-Free Smoothed Particle Hydrodynamics

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

   Författare :Theo Holmqvist Berlin; [2021]
   Nyckelord :SPH; regional time stepping; divergence free; simulation;

   Sammanfattning : Background. Fluid simulation is an area of ongoing research. In recent years, simulators have become more realistic and stable, partly by employing the condition of having divergence-free velocity fields. A divergence-free velocity field is a strict constraint that requires a high level of correctness in a simulation. LÄS MER

3. 2. A constraint based viscoplastic model of granular material

   M1-uppsats, Institutionen för fysik

   Författare :John Nordberg; [2011]
   Nyckelord :granular matter; constraint based sph; viscoplastic fluid model;

   Sammanfattning : The goal of this thesis is to develop a constraint based viscoplastic fluid model suitable for time-efficient dynamics simulation in 3D of granular matter. The model should be applicable to both the static and dense flow regime and at large pressures. The thesis is performed for UMIT Research Lab at Umeå University. LÄS MER
