A Moving Mesh Numerical Method
We show that the possibly discontinuous solution of a scalar conservation law in one space dimension may be approximated in i-'(R) to within 0(N~2) by a piecewise linear function with O(N) nodes; the nodes are moved according to the method of characteristics. We also show that a previous method of Dafermos, which uses piecewise constant approximations, is accurate to 0(N~l). These numerical met...
متن کاملMoving-mesh cosmology: properties of neutral hydrogen in absorption
We examine the distribution of neutral hydrogen in cosmological simulations carried out with the new moving-mesh code AREPO and compare it with the corresponding GADGET simulations based on the smoothed particle hydrodynamics (SPH) technique. The two codes use identical gravity solvers and baryonic physics implementations, but very different methods for solving the Euler equations, allowing us ...
متن کاملCase Study: A Visual Tool for Moving Mesh Numerical Methods
Time-dependent partial differential equations are indispensable in scientific and engineering research, where they are used to model physical phenomena such as fluid flow and combustion. Moving mesh numerical solution methods have proven to be particularly well-suited to compute solutions to such problems which change non-uniformly over time. Computer visualization of moving mesh methods is an ...
متن کاملMoving Five-branes and Cosmology *
We discuss low-energy heterotic M-theory with five-branes in four and five dimensions and its application to moving brane cosmology.
متن کاملMesh Moving Techniques for Fluid-Structure Interactions With Large Displacements
In computation of fluid-structure interactions, we use mesh update methods consisting of mesh-moving and remeshing-as-needed. When the geometries are complex and the structural displacements are large, it becomes even more important that the mesh moving techniques are designed with the objective to reduce the frequency of remeshing. To that end, we present here mesh moving techniques where the ...
