Having used Geant4 for about 10 years, I thought that a tool with a UI design similar to RStudio, which helps one to insert detectors, create materials, shoot particles and also to analyze data in a single interface without any coding would be useful to many. Additionally, if the process of downloading and compiling Geant4 could be reduced, it would ease up things. Towards this goal, I built a tool (codename “simple”) which will let you build your simulations without compiling Geant4 or ROOT and without writing any code!
The application is available as an AppImage here: https://github.com/deepaksamuel/simple/releases/download/v0.1-alpha/Simple-x86_64.AppImage.
AppImages are what executables are for Windows. No need to compile or download Geant4 or ROOT. Just download and double click the app image and you are ready to go!
You can use it for creating simple geometries and fast simulations of particle interactions with matter. A simple ROOT-based plotting interface is also built-in. Data from the detectors can be exported to ASCII format. It can be useful for demonstrations in particle and medical physics.
The code is opensource and is now available at https://github.com/deepaksamuel/simple along with usage instructions.
