20-Year Commitment (2008~2028): Boost CAE/CFD simulation resolution by two orders of magnitude
The Rankyee Technology team began collaboration at Tsinghua University in 2008, aiming to develop a new generation of computational fluid dynamics software that can replace international products. After eighteen years of continuous efforts and five generations of algorithm evolution,we have completed the full workflow from algorithm innovation and laboratory research, full industrial software development, to top-tier international industrial application and validation.

Over eighteen years, DIMAXER has advanced through the stages of "Foundation Building · Practical Deployment · Boundary Breaking · Cost Reduction · Industry Leadership"
Bringing industrial simulation into the era of high-resolution system-level simulation. Each iteration moves one step further toward a more efficient and precise industrial future.
During doctoral research at Tsinghua University, the founding team initiated R&D of a new generation of Computational Fluid Dynamics (CFD) algorithms, centered on local reconstruction high-precision methods.
While studying at Tsinghua University and the University of Cambridge, the first-generation algorithm was completed: the world’s first high-order accuracy solver supporting hybrid unstructured meshes including pyramid elements.
During postdoctoral research at the University of Cambridge, the space-time integrated flux reconstruction numerical method was proposed, achieving linear growth of computational cost with simulation scale and scale difference. The second-generation algorithm was released: the world’s first high-order accuracy solver capable of solving complex engineering problems.
DIMAXER was founded to launch the third-generation algorithm. Built upon the space-time integrated, kinetic energy conserving flux reconstruction framework, full GPU parallel refactoring was completed, greatly improving the stability and efficiency of solving complex flow problems.
The founding team returned to China full-time and assembled a complete industrial simulation software R&D team covering solver, pre-processing and post-processing modules.
The 4th-generation algorithm was released, delivering over 20x speedup on a single GPU. At the Suzhou product launch in August 2023, a live demonstration showed high-fidelity large eddy simulation completed within one hour on a single GPU card.
Functions including multi-physics coupling, dynamic interfaces, combustion modeling and dynamic immersed boundary were developed. At the Beijing launch in December 2024, the full CAE software suite was unveiled. Using 40 consumer GPUs, we completed low-cost large eddy simulation of 5/6-stage full annular compressors and high-fidelity full-aircraft LES for large aircraft with over 2.5 billion body-fitted mesh nodes.
Energy efficiency benchmark: a single desktop GPU (approx. 1kW total power consumption) supports high-fidelity simulation with 100 million solution points. With a small self-built cluster in Suzhou, we completed low-cost validation for hundred-billion-point simulation. DIMAXER software has entered large-scale engineering deployment with leading clients in high-end equipment sectors including aerospace, marine, nuclear power, aero-engines, solid rocket motors, power equipment, boilers, wind power and UAVs.
The complete 5th-generation algorithm system is scheduled for release to further drastically accelerate computation and enhance core features including multiphase flow, fluid-structure interaction and long physical-time simulation. A cloud computing platform and simulation knowledge base system will be rolled out simultaneously to greatly improve software usability and support free trial access.
