Pandat Software: CALPHAD-based materials design

The architecture of Pandat software consists of three layers: the interface layer, the application layer, and the database layer. This type of architecture leads to the good extendibility and maintainability of Pandat software. It allows for the parallel development of individual layers and having different experts focus on each of these three layers significantly increases the overall quality of Pandat. This reduces any subsequent development efforts, minimizes the maintenance workload and decreases migration costs when switching client applications, e.g., from a conventional desktop application to a web application.

Pandat software adopts modular design and currently includes 6 modules: PanPhaseDiagram for phase diagram and thermodynamic property calculation, PanEvolution for precipitation and recrystallization simulation, PanDiffusion for diffusion simulation, PanSolidification for solidification simulation, PanOptimizer for property optimization and PanPhaseField for phase field simulation. This unique design enables users to easily switch between modules and perform variety types of simulations in the same workspace. Pandat software has a robust calculation engine and a friendly graphical user interface, and it is known as the most reliable and easy to use software in this field.
