2021–2023
THE BEGINNING
An Ambition to Advance Particle Simulation
GranDEM was founded with a clear ambition: to develop and market advanced Discrete Element Method (DEM) software for unstructured grids. The vision was to build a Software as a Service (SaaS) company around specialized engineering simulation technology.
The Foundation
Establishing the vision for advanced DEM-based engineering simulation.
2022–2024
INTEGRATION & FIRST RELEASE
Bringing Simulation Tools Together
Yara took an interest in the project and initiated a one-year funded GUI development project. The goal was to bring key simulation capabilities together through a single GranDEM interface.
The DEM was API-coupled with the Ansys Fluent fluid flow solver and the HEFTY granulation model, allowing these components to be controlled through the GranDEM GUI. A separate ParaView autoload application was also developed for visualization postprocessing.
JANUARY 2024
GranDEM v1.0
Trial version provided to Yara.
JUNE 2024
Licensing Begins
Licensing sales to Yara commenced following a satisfactory trial.
2025–2026
A NEW PRODUCT IDENTITY
Expanding Beyond DEM Simulation
In 2025, the founder left his job and began focusing on developing the SGE fluid flowsolver. This marked an important stage in the evolution of the product, expanding its simulation capabilities beyond the existing DEM solver.
In January 2026, the first SGE fluid flowsolver version was released alongside GranDEM v2.0, supporting compressible flow, energy transfer and multicomponent capabilities.
Coupled Simulation
A demonstration combining the DEM solver with the SGE fluid flowsolver was developed and released.
LATEST MILESTONE IN THE DOCUMENT
GranDEM v2.2 → LnEFlow
With the v2.2 release, GranDEM was renamed LnEFlow, marking the next stage in the product's evolution.
