This tool is an integrated graphical interface that simplifies molecular dynamics simulations using Gromacs. It provides a structured, tab-based environment to set up, execute, and analyze simulations data without complex command-line operations. The software automates tasks such as topology generation, solvation, ion addition, minimization, equilibration, and production runs while executing GROMACS commands in the background. Built-in monitoring tracks CPU, RAM, and disk usage to ensure stable performance during parallel processing. Beyond simulation execution, it includes advanced trajectory processing and analysis tools such as RMSD, RMSF, SASA, clustering, PCA, hydrogen-bond analysis, Ramachandran plots, and FEL mapping. With integrated visualization and plotting utilities, it offers a unified platform for researchers, educators, and students to perform complete MD workflows efficiently and reproducibly. Our Goal is to bring MD simulations to every biologist's toolkit.

The GNNPCSAFT Web App is an implementation of our project that focuses on using Graph Neural Networks (GNN) to estimate the pure-component parameters of the Equation of State PC-SAFT. We developed this app so the scientific community can access the model's results easily. In this app, the estimated pure-component parameters can be used to calculate thermodynamic properties and compare them with experimental data from the ThermoML Archive. - CPU-compatible desktop build The standard desktop release requires AVX2. For older CPUs, the runtime-compatible variant can be found with the suffix "-rtcompat-".

SimFPGA is a graphical user interface (GUI) tool designed to facilitate the simulation of VHDL projects. It enables users to select VHDL source files and testbenches, configure library and standard settings, and run simulations using GHDL. Additionally, it allows visualization of waveforms through GTKWave. SimFPGA elaborates the project files using GHDL and builds the VHDL project before simulating it. This ensures code verification without the need for additional compilation tools. If an error is detected in any of the project files during elaboration or simulation, a message is displayed in the console indicating the type and location of the error, allowing the user to quickly resolve it.

LaserFoam performs simulations of laser pulses using an adaptive split step Fourier method to solve the generalized nonlinear Schrödinger equation. It provides a graphical environment to run and visualize the results.

This project has been moved to: https://github.com/fmipp/powerfactory-fmu The FMI++ PowerFactory FMU Export Utility is a stand-alone tool for exporting FMUs for Co-Simulation (FMI Version 1.0 & 2.0) from DIgSILENT PowerFactory models. It is open-source (BSD-like license) and freely available. It is based on code from the FMI++ library and the Boost C++ libraries. 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).
