  • Construct2D

    COmputational fluid dyNamics STRUctured grid CreaTor for 2D airfoils

    Construct2D is a grid generator designed to create 2D grids for CFD computations on airfoils. The grids are generated in Plot3D format. The only required input file is the set of coordinates defining the airfoil geometry, using the same format as XFoil, the popular vortex-panel code for airfoil analysis. Construct2D can create grids with O topology (recommended for airfoils with a blunt trailing edge) or C topology (recommended for airfoils with a sharp trailing edge). Now available in version 2.0: hyperbolic grid generation to create higher quality grids in a fraction of the time compared to elliptic grid generation. Elliptic grid generation is still available also. Smooth airfoil surface spacing is handled automatically with user-controlled clustering parameters. Also included is a visualizer written in Python with matplotlib.

  • Fosite - 2D advection problem solver

    numerical simulation code solving transport equations in 2D

    fosite is a generic framework for the numerical solution of 2D hyperbolic conservation laws in generalized orthogonal coordinates. Its main purpose is the simulation of compressible flows with either rotational symmetry or slab symmetry. The underlying numerical solution method belongs to the family of unsplit conservative finite volume TVD schemes. The method is 2nd order accurate in space and uses high order Runge-Kutta and multistep schemes for time evolution. In addition to the pure advection code several source terms have been implemented including viscous diffusion and gravitational acceleration. Due to its modular object-oriented design it is very easy to add new features to the code.

  • freesrs

    python library for shock response spectrum (SRS) analysis.

    The shock response spectrum (SRS) allows to estimate transient acceleration signals in terms of a maximum response of a dynamic vibration system. Its origin probably dates from civil engineering and the problem of seismic excitations, i.e. earthquake response of buildings, see Clough Penzien 1975. The SRS is a spectrum, i.e. a curve giving the maximum acceleration response depending on frequency. It is derived from a 1-mass-spring-damper vibration system being excited by a base excitation, i.e. an acceleration. freesrs calculates the shock response spectrum (SRS) and is a small library with Python and Fortran files. The Fortran files consist of • SmallwoodFilter.f and • GenShockTimeHistories.f They are linked to Python by using the comfortable f2py tool. Latest version is 1.1.1, including now the ability to perform a full install via
