The development of domestic independent CAE simulation software is at a critical turning point. As the high-end manufacturing industry demands increasingly higher simulation accuracy, a self-controlled and reliable simulation software foundation has become ever more important.

Industry Landscape

For a long time, the domestic CAE market has been dominated by foreign commercial software such as ANSYS, Abaqus, and Nastran. These tools are powerful, but they present the following issues:

  1. High cost — Commercial license fees are prohibitively expensive, making them unaffordable for many small and medium-sized enterprises
  2. Technology restrictions — Some advanced features are restricted for Chinese users
  3. Difficult customization — Closed-source software struggles to meet specific industry needs

Advantages of Independent Simulation Software

Full Autonomy and Control

From underlying algorithms to upper-level interfaces, the entire stack is developed in-house, free from external dependencies.

Flexible Customization

Deep customization can be carried out according to the specific needs of domestic manufacturing, such as:

  • Constitutive models for specific materials
  • Industry-standard verification workflows
  • Data interoperability with domestic CAD software

Cost Optimization

Compared to foreign commercial software, independent simulation software offers clear advantages in both procurement and maintenance costs.

Technical Challenges

Developing a truly usable independent finite element solver requires overcoming the following hurdles:

  • Large-scale sparse matrix solving
  • Nonlinear iteration convergence
  • Multiphysics coupling algorithms
  • High-performance parallel computing

Future Outlook

With increasing national policy support for industrial software independence and the continuous accumulation of domestic CAE talent, independent simulation software will enter a period of rapid development over the next 5–10 years.
