AcuSolve™ is a leading general-purpose finite element-based Computational Fluid Dynamics (CFD) flow solver with superior robustness, speed, and accuracy. AcuSolve can be used by designers and research engineers with all levels of expertise, either as a standalone product or seamlessly integrated into a powerful design and analysis application. With AcuSolve, users can quickly obtain quality solutions without iterating on solution procedures or worrying about mesh quality or topology.

Key Benefits
  • Robustness - Most problems solved on the first attempt
