Description
Geant4 is an object-oriented C++ toolkit widely used for simulating the passage of particles through matter, especially in nuclear physics research. However, its application requires a high level of programming proficiency, which often hinders broader adoption in scientific work. To lower the technical barriers associated with Geant4, we previously introduced a wizard-style GUI and modular design in eCARD (easy CAlculator of RaDiation). In its latest version, eCARD has been significantly enhanced with visual modeling and simulation data visualization capabilities. It now supports wizard-guided radiation field modeling in Windows environments and assists in studying the influence of geometry, dimensions, particle incidence angles, and energy on radiation measurement, effects, dose, and shielding. Through its interactive interface, the software enables intuitive application invocation and parameter configuration, facilitating rapid radiation modeling and analysis. This work presents the updated design of eCARD and explains its adaptability across various research fields. The implementation and practical applications are described, followed by a comparison of simulation results with research cases and a discussion of the outcomes.
