RFPA: Reshaping Engineering Simulation with Chinese Innovation

I. Breaking the Monopoly: China's Independent Path in Engineering Simulation

For a long time, China's engineering simulation market has been monopolized by foreign commercial software. Although internationally renowned software such as ABAQUS and ANSYS are powerful, they have many problems:

The Dilemma of Technical Blockade

• High licensing fees: A single software license can cost hundreds of thousands or even millions of yuan
• Black box core algorithms: Unable to access source code, difficult to customize development according to project needs
• Limited technical support: Key technical issues cannot be resolved in a timely manner
• Data security risks: Important engineering data may face leakage risks

The Birth Background of RFPA

RFPA (Rock Failure Process Analysis) was developed by Professor Tang Chun'an's team at Dalian University of Technology over more than 20 years, focusing on numerical simulation analysis in the fields of geotechnical engineering, geological disasters, and mining engineering.

Core Concept: Based on material micro-heterogeneity and damage mechanics theory, it truly reproduces the entire process of rock materials from micro-crack initiation, propagation, coalescence to final failure.
