  2. 1. Stability and boundedness results for variable-step variable-formula methods

    Author : Jørgen Sand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This work constitutes the author's Doctoral thesis, which includes an introduction to and a summary of the following two TRITA-NA-reports: 8112 and 8218.In many practical applications one is interested in step-wise simulation of the behaviour of a dynamic system described by ordinary differential equations.

  4. 2. Construction of Adaptive Multistep Methods for Problems with Discontinuities, Invariants, and Constraints

    Author : Fatemeh Mohammadi; Numerisk analys; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multistep methods; Initialization; beta-blocking; Discontinuity; Time adaptivity; Strong stability preserving; Differential algebraic equations;

    Abstract : Adaptive multistep methods have been widely used to solve initial value problems. These ordinary differential equations (ODEs) may arise from semi-discretization of time-dependent partial differential equations(PDEs) or may combine with some algebraic equations to represent a differential algebraic equations (DAEs).

  5. 3. Partitioned methods for time-dependent thermal fluid-structure interaction

    Author : Azahar Monge; Numerisk analys; []
    Keywords : thermal FSI; Conjugate heat transfer; Domain decomposition; Time adaptivity; Coupled problems; multirate;

    Abstract : The efficient simulation of thermal interaction between fluids and structures is crucial in the design of many industrial products, e.g. turbine blades or rocket nozzles. READ MORE

  6. 4. A Software Framework for Implementation and Evaluation of Co-Simulation Algorithms

    Author : Christian Andersson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulation; Co-Simulation; Assimulo; JModelica.org;

    Abstract : In this thesis, simulation of coupled dynamic models, denoted sub-systems, is analyzed and described in a co-simulation context. This means that the respective coupled systems contain their own internal integrator, hidden from the coupling interface. Co-Simulation is an interesting and active research field where industry is a driving force. READ MORE
