Fidelity CFD Mesh Adaptation that Respects Geometry and Reduces Runtime

Mesh adaptation is a common technique employed to help improve simulation efficiency. Unstructured mesh adaptation has been used to reduce the mesh size to reach the desired solution accuracy. This technique enables significant improvements in processing time, memory requirements, and storage needed. However, without access to the underlying CAD data, adaptation is limited only to improving off-body grid resolution. While the mesh adaptation technique in Fidelity CFD respects the geometry, improves the mesh quality, adapts to the near-wall shear layers, and reduces run-time for improved CFD solutions. READ MORE

Play by the Rules – Identify and Fix Mesh Quality Issues Right Away!

The Golden Rule of mesh generation is to produce a mesh that provides a foundation for an accurate and converged computational fluid dynamics (CFD) solution. One might say that meshing experts know how to enforce the Golden Rule. On the contrary, only a CFD practitioner can tell whether the mesh is suitable for analysis. The physical models, the solver algorithm, the grid type, the available computer resources, desired outputs, desired level of accuracy, organization's best practices determine a grid's acceptability. Using Fidelity Pointwise’s Rules command, one can monitor and verify the specified grid requirements at any time during the meshing process. READ MORE

Adhering to User Preferences with Entity Selection

It is often a cumbersome task to select the entities that ought to be modified individually. But with Fidelity Pointwise, every aspect of a CFD grid can be manipulated. It has tools beyond the traditional point-and-click to help users quickly select and work with objects individually and collectively for quick and efficient management of various entities. READ MORE

Success Stories

EV Maritime - Decarbonizing the Harbors of the World with Electric Ferries Designed with Fine Marine

Auckland, New Zealand’s EV Maritime is not just developing high-performance electric boats; they are looking to help cities transform their transport systems, providing cleaner and more efficient mass transit options to help us all out of our private vehicles and into active and public transport. These days, computational fluid dynamics (CFD) simulation is the fastest, most accurate, and most powerful tool to explore design variations for efficient hull shapes. EV Maritime chose Cadence's Fine Marine for their CFD simulations because they trust Cadence's results above others when it comes to modeling the surface wave effects that are critical to their vessels.

CelSian’s Glass Furnace Simulations on Pointwise Grids Celebrate 2022, the International Year of Glass

Computational Fluid Dynamics (CFD) continues to extend its reach in different domains, and with CelSian’s simulation software, GTMX, it is possible to simulate and analyze the physics inside a glass furnace. GTMX has dedicated models that allow furnace designers to predict the factors affecting production time and quality. CelSian uses Cadence Fidelity Pointwise as the mesh generation software for refinement in locations where the physics is crucial for the glass production process. Using a computer simulation technology wherein the CAD import and meshing are carried out in Fidelity Pointwise, and the simulation is solved on GTMX, different models with multiple design criteria can be tested within the time constraints.
