    1 Abstract We describe a procedure for the adaptive h refinement solution of the incompressible MHD equations in stream function form using a stabilized finite element formulation The mesh is adapted based on a posteriori spatial error estimates of the magnetic field using both recovery and order extrapolation techniques The step size for time integration is chosen so that temporal discretization errors are small relative to spatial errors The adaptive

  • RPI SCOREC - Technical Reports
    Physics Conference Series Volume 78 Pages 012053 Abstract This paper discusses methods being developed by the ITAPS center to support the execution of parallel adaptive simulations on unstructured meshes The paper first outlines the ITAPS approach to the development of interoperable mesh geometry and field services to support the needs of SciDAC application in these areas The paper then demonstrates the ability of unstructured adaptive meshing methods built on such

    differential equations requires accessing manipulating and often modifying information about the geometry of the computational domain the mesh used for the simulation and discrete data stored on that mesh Typically applications programmers would prefer to avoid the difficulty and complexity of creating their own modules for tasks like interacting with multiple geometric modelers mesh adaptation and optimization algorithms rightly preferring instead to focus on the problem physics and on studying
