OpenCRG is a complete free and open-source project for the creation, modification and evaluation of road surfaces, and an open file format specification CRG (curved regular grid). Its objective is to standardize a detailed road surface description and it may be used for applications like tire-, vibration- or driving-simulation.
The short MATLAB script below illustrates how a complete flow around a cylinder computational fluid dynamics (CFD) benchmark problem can be defined and solved with the FEATool m-script functions (including geometry, grid generation, problem definition, solving, and postprocessing all in a few lines of code).
MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities.
This scheme involves the placement of electric and magnetic fields on a staggered grid. Finite-difference time-domain ( FDTD ) or Yee's method (named after the Chinese American applied mathematician Kane S. Yee , born 1934) is a numerical analysis technique used for modeling computational electrodynamics (finding approximate solutions to the ...
Grid search then trains an SVM with each pair (C, γ) in the Cartesian product of these two sets and evaluates their performance on a held-out validation set (or by internal cross-validation on the training set, in which case multiple SVMs are trained per pair). Finally, the grid search algorithm outputs the settings that achieved the highest ...
The grid file contains the coordinates of the solution grid, while the solution file contains information typical of a CFD solution, flow density, flow momentum (a vector), and flow energy. [2] Data may be stored in either binary or ASCII text format and floating point values may be either single or double precision.
Adaptive mesh refinement (AMR) changes the spacing of grid points, to change how accurately the solution is known in that region. In the shallow water example, the grid might in general be spaced every few feet—but it could be adaptively refined to have grid points every few inches in places where there are large waves.
Interfaces to netCDF based on the C library are also available in other languages including R (ncdf, [7] ncvar and RNetCDF [8] packages), Perl Data Language, Python, Ruby, Haskell, [9] Mathematica, MATLAB, Interactive Data Language (IDL), Julia and Octave. The specification of the API calls is very similar across the different languages, apart ...
