    Note: Active projects have been copied to Github: https://github.com/pcraster News, project information, documentation and more are available at http://www.pcraster.eu PCRaster is a collection of tools and software libraries tailored to the construction of spatio-temporal environmental models. Application domains are amongst others hydrology (rainfall-runoff, global water balance, groundwater (with Modflow)), ecology, or land use change. Two scripting languages (PCRcalc and Python) include a rich set of spatial operations for manipulating and analysing raster maps. A Python framework supports Monte Carlo simulations and data assimilation (Ensemble Kalman Filter and Particle Filter). The Aguila tool allows for the interactive visualisation of stochastic spatio-temporal data.

    QWait (theme park visitor simulator)

    Simple theme park visitor simulator

    ...What's included: Visitor will travel from ride to ride at a reasonably realistic speed. There are several different types of visitor, and they will have different ride requirements. There are two types of rides being simulated: continuous (like the awesome "it's a small world" and show (eg Lion King) What's not included (yet?): Food/drink. Accurate paths, visitors currently travel in straight lines. Future? I would like to add all the missing stuff, and more theme parks. View positions of each visitor minute by minute (report already exists for this, but no way to view the data visually). ...

    Epidemic-Simulation

    Epidemic-Simulation

    Simulate an epidemic like the Corona Pandemic and look at statistics

    With Epidemic-Simulation you can look at the development of a corona-like epidemic or pandemic, impose a lockdown and follow the statistics. When imposing a lockdown there will be a marker in the statistics about the beginning and the end of the lockdown. There is a simple movement simulation of the people. If a susceptible person gets close to an infected person their viral load increases and they might get infected. This software is very new and will be updated from time to time....

    Parallel simulators for Membrane Computing on the GPU

    Membrane Computing is a new research area (within Natural Computing) that aims to provide computing devices abstracted from the functioning and structure of living cells. These devices are called P systems. The objective of this project (PMCGPU) is to bring together all the researchers working on the development of parallel simulators for P systems, specially those using the GPU (e.g. CUDA, OpenCL, etc). Other parallel platforms are also welcome (multicore and manycore, FPGAs,...

    powerfactory-fmu

    The FMI++ PowerFactory FMU Export Utility

    ...The FMI++ PowerFactory FMU Export Utility provides a graphical user interface (new in version v1.0) and - alternatively - Python scripts that generate FMUs from certain PowerFactory models. Additional files (e.g., time series files) and start values for exported variables can be specified. Currently, two types of simulations are supported: In quasi-static steady-state simulations a power system’s evolution with respect to time is captured by a series of load flow snapshots. RMS simulations allow to calculate the time-dependent dynamics of electromechanical models, including control devices (new in version v0.6).

    Waves FX

    Advanced 2D simulator for evolving harmonical waves.

    ...Some of the "normal" features are XY scalation, manual or mouse-assisted, translation of the XY axes, change of background colors, dynamic range X and DX, etc. The program is bi-threaded at run-time with 2 cooperative threads: background + foreground, that allows that all user-input parameters (including change of the virtual-time!) are automatically updated at run-time.

    ParamIT

    a Toolset for Molecular Mechanical Force Field Parameterization

    ParamIT is a toolkit aiding the development of molecular mechanical force field parameterization of small, drag like, molecules within CHARMM general force field (CGenFF) protocol. The developed toolkit helps the researchers in following ways: 1) automating the creation of multiple input files for quantum and molecular mechanics programs, 2) automating the output analysis and 3) substitute the use of full MM programs with a faster specialized one. The developed tools include: 1) generator of molecule-water complexes with graphical user interface (GUI), 2) semi-automatic frequency analysis using symbolic potential energy distribution matrix and comparison of optimized internal coordinates, 3) GUI for charge fitting with three modes: manual, Monte-Carlo sampling or brute force, and 4) GUI for dihedral terms fitting. ...

    Prediction of proteinfolding in 2D HP model

    Even in the simplified two dimensional HP-model (hydrophob/polar) the prediction of proteinfolding is NP complete. We implement a brute force algorithm with serial and parallel execution to solve short inputs of HP sequences (0-1 bitstrings). Selbst im vereinfachten zweidimensionalen HP-Modell (hydrophob/polar) ist die Proteinfaltung bereits NP-vollständig.

    CCruncher

    CCruncher

    Open-Source Project for Credit Risk Modeling

    CCruncher is a project for quantifying portfolio credit risk using the copula approach. It is a framework consisting of two elements: a technical document that explains the theory, and a software program that implements it. CCruncher evaluates the portfolio credit risk by sampling the portfolio loss distribution and computing the Expected Loss (EL), Value at Risk (VaR) and Expected Shortfall (ES) statistics. The portfolio losses are obtained simulating the default times of obligors and simulating the EADs and LGDs of their assets.
