Industry Challenges

Difficulty balancing computational efficiency and accuracy

Traditional CFD methods suffer from slow computation and insufficient accuracy when simulating high-Reynolds-number turbulent flows such as full-vehicle external flow fields. It is hard to resolve complex flow details including flow separation and reattachment

High hardware costs

High-precision simulation relies on top-tier supercomputers, imposing unaffordable hardware investment for SMEs

Complex multi-physics coordination

Multiple scenarios including structural simulation, thermal management and on-chip cooling require cross-module collaboration, resulting in cumbersome workflows and potential error introduction

Solution Overview

Powered by core technologies of LES transient simulation and native GPU support, DIMAXER software provides fast, high-fidelity and low-cost integrated simulation solutions for automotive R&D.

It helps optimize aerodynamic performance, reduce noise, improve thermal management efficiency and accelerate product iteration, promoting the upgrade of automotive design from "approximate estimation" to "accurate prediction".

Solution Advantages

LES Transient Simulation + High-order Algorithms

Large Eddy Simulation (LES) directly resolves vortex generation and dissipation. Combined with 4th/8th-order accurate solvers, it recovers fine flow fields such as separation and reattachment on coarse meshes, delivering notably higher accuracy than RANS methods.

Native GPU Acceleration

With efficient GPU parallel computing, supercomputer-level tasks (e.g. full vehicle external flow simulation with 110 million solving points) can be completed on low-cost consumer GPUs such as RTX 4090 or small clusters. Hardware cost is reduced to 1/100 of traditional solutions.

Multi-block Overset Mesh Technology

Flexibly decomposes complex geometries including car body, rearview mirrors and tires. Near-wall unstructured hexahedral meshes overlap with Cartesian background meshes to avoid degraded near-wall mesh quality and improve simulation reliability.

Integrated Multi-physics Module

Integrates aerodynamic noise analysis, structural simulation, thermal management and on-board chip cooling simulation, enabling one-stop analysis for multiple scenarios and shortening R&D cycles.
