Advanced Design Optimization

Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) have been widely used almost in every industrial field to assess the performance of products, analyze and predict failures.

Our CFD/FEA-based design optimization technology integrates our proprietary automatic mesh generators, 3D inverse and direct design tools, parameterized geometry models, target functions, and hemolysis and thrombosis models with commercial software, such as ANSYS®. This state-of-the-art approach provides a far more efficient means of optimization, simulations, and modeling than traditional methods. It has been successfully applied to the design and developemnt of numerous adult and pediatric left ventricular assist devices (LVADs), RVADs, percutaneous VADs, total hearts, and other medical devices, bioengineering, green energy, turbomachinery, and many other industrial products.

Our proprietary automatic elliptic mesh generators can quickly generate high-quality 3D multi-block structured grids featured with boundary orthogonality and local clustering around bodies. Such grids guarantee the accurate CFD prediction of complex flow in the boundary layers adjacent to the wall surfaces.

Our proprietary 3D direct and inverse design tools with parameterized mathematical geometry models can quickly create or compute the shapes of impeller and stator blades, and other components of a turbo-machine.

Our state-of-the-art CFD/FEA-based design optimization is further enhanced by the integration of target functions, which directly link the performance parameters of a design to the parameter matrix of geometry, thus greatly facilitating and expediting the iterative process of optimization.

For blood pumps and other medical devices delivering blood, we use the blood damage models by Lagrangian or Eulerian methods to accurately evaluate shear-induced hemolysis. Our thrombosis modeling can accurately simulate the process of platelet deposition and thrombus growth in blood pumps and other blood flow devices.
