...It allows you to import data from Bruker spectrometers such as Elexsys or EMX and data from any ASCII file or imported from the clipboard. The program is under constant development, but already has many functions implemented for spectral analysis. Some of the basic functions include: baseline corrections, filtering, spectral clipping, integration / differentiation, pseudomodulation, filtering, etc. More advanced functions are: Forward / Inverse Fourier Transforms, Hilbert Transforms, Nonlinear Curve Fit, Global Analysis Fit of Multiple Curves, and many other. It is also possible to create your own plugins extending Eleana's functionality.

Important: Groimp migrates to Gitlab. You can find the latest code at "https://gitlab.com/grogra/groimp/". The version on Sourceforge will not be updated anymore. The modelling platform GroIMP is designed as an integrated platform which incorporates modelling, visualisation and interaction. It exhibits several features which makes itself suitable for the field of biological or ALife modelling: The “modelling backbone” consists in the language XL. It is fully integrated, e.g., the...

MATLAB code that generates all figures in [Almquist and Dunham, 2020, https://doi.org/10.1016/j.jcp.2020.109294 ]. The paper considers narrow-stencil summation-by-parts finite difference methods and derives new penalty terms for boundary and interface conditions. The new penalty terms are significantly less stiff than the previous state-of-the-art method on curvilinear grids. On highly skewed grids, there may be an order of magnitude or more difference in the time-step restriction.

A spectral element method for 2D wave propagation and fracture dynamics, with emphasis on computational seismology and earthquake source dynamics.

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.

A brief summary of the main features of Fesslix: - Perform non-intrusive reliability analysis or Bayesian updating either --- by running commands on the command line or --- by means of an Octave interface or --- by means of a Python interface - Flexible input language for writing Fesslix parameter files --- Control flow statements (e.g. if, for, while) --- Most parameters can be defined as functions - Working with response surfaces - Linear finite element analysis using truss, beam and plane stress/strain elements - Spectral Stochastic Finite Elements - Bayesian networks This is the download page for Windows executables of Fesslix.

Sempy is a Python package for the solution of partial differential equations using the spectral element method.

Virtuelium is an open-source multi-spectral physically based ray-tracer developed to render the visual appearance of material and to be able to do multi-scaled simulations of light interactions.

The makhno project is an implementation of a framework for the solution of partial differential equations using spectral/hp element high-order methods. Primary purpose is the solution of Navier-Stokes equations

CFD scientific software. Provides simulation of 3D CFD problem based on Quasi-Gas Dynamics approach with radiation processes token into account. Lots of spectral intervals are considered. Parallel MPI/OpenMP-based implementation is provided.

This is a spectral solver of Channel flow with options of Rotation and Stratification (CRS).

A repository of Direct Numerical Simulation codes (Full solutions of the Navier Stokes Equations in fluid dynamics) in various geometries using a mix of high-order finite-difference and spectral methods.

A set of self-contained C++ routines to sample and resolve functions properly for plotting, as well as curve fitting routines that fit spectral features. This is mainly useful for scientific simulations where spectral data need to be fully resolved.

A solver based on the spectral element method, used in conjunction with FEMAP, as a pre- and post- processor. It solves the elastic wave propagation problem, and the coupling with a piezoelectric materials for excitation and sensing. It is currently in 2D and has both static and transient capabilities.
