  2. 1. Cut Finite Element Methods on Overlapping Meshes: Analysis and Applications

    Author : Carl Lundholm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parabolic problem; multi-objective optimization; multi-mesh; energy analysis; CutFEM; augmented reality; overlapping meshes; moving meshes;

    Abstract : This thesis deals with both analysis and applications of cut finite element methods (CutFEMs) on overlapping meshes. By overlapping meshes we mean a mesh hierarchy with a background mesh at the bottom and one or more overlapping meshes that are stacked on top of it. READ MORE

  4. 2. Adaptive finite element methods for parameter estimation problems in partial differential equations

    Author : Tao Feng; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parameter estimation; ¯nite element approximation; adaptive ¯nite element methods; a posteriori error estimates; least squares.; MATHEMATICS; MATEMATIK;

    Abstract : Physical and chemical phenomena are often described by a system of partial di®erential equations. These equations usually involve unknown parameters, which cannot be measured directly but which can be adjusted to make the model predictions match the observed data. READ MORE
