    • Computing Bounds for Linear Functionals of Exact Weak Solutions to Poisson’s Equation 

      Sauer-Budge, A. M.; Bonet, J.; Huerta, A.; Peraire, J. (Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 2003)
      We present a method for Poisson’s equation that computes guaranteed upper and lower bounds for the values of linear functional outputs of the exact weak solution of the infinite dimensional continuum problem using traditional ...

    • Output-based Adaptive Meshing Using Triangular Cut Cells 

      Fidkowski, Krzysztof J.; Darmofal, David L. (Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 2006-10)
      This report presents a mesh adaptation method for higher-order (p > 1) discontinuous Galerkin (DG) discretizations of the two-dimensional, compressible Navier-Stokes equations. The method uses a mesh of triangular elements ...

    • Model-Constrained Optimization Methods for Reduction of Parameterized Large-Scale Systems 

      Tan, Bui-Thanh (Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 2007-05)
      Most model reduction techniques employ a projection framework that utilizes a reduced-space basis. The basis is usually formed as the span of a set of solutions of the large-scale system, which are computed for selected ...
