Advanced Meshing Capabilities

Structured and Unstructured Mesh Generation

Fidelity Pointwise provides a suite of advanced meshing technologies designed to handle diverse geometric complexities and simulation requirements. The software supports the generation of various mesh types, including structured and unstructured grids, which are fundamental for accurate CFD computations.

• Hexahedral Meshes: Capable of generating all-hexahedral meshes, these grids offer superior accuracy for certain flow physics and boundary layer resolution.
• Quadrilateral Meshes: Facilitates the creation of quadrilateral surface meshes, often a preferred starting point for structured volume meshing.
• Prism Meshes: Essential for resolving boundary layers, Fidelity Pointwise allows for the generation of anisotropic prism layers that conform to surface geometry.
• Tetrahedral Meshes: Supports the generation of tetrahedral volume meshes, which are versatile for complex geometries where hexahedral meshing is challenging.

Integration with CAD Software

Seamless integration with existing design workflows is a key aspect of Fidelity Pointwise’s utility. The software is engineered to import and process geometric data from a wide range of Computer-Aided Design (CAD) systems, accommodating both analytical and faceted representations of a model. This compatibility ensures that engineers can begin the CFD analysis process without extensive geometric cleanup or reconstruction.

• The software supports various CAD file formats, enabling the import of geometries from industry-standard tools.
• It can work with both analytical geometry (defined by mathematical equations) and faceted geometry (represented by triangular or quadrilateral facets), offering flexibility in handling different data types.

Use of T-Rex Technology

A standout capability within Fidelity Pointwise is its proprietary T-Rex (anisotropic tetrahedral extrusion) technology. This advanced meshing methodology is specifically designed to automate the generation of high-quality, anisotropic meshes, particularly in regions requiring fine resolution, such as near walls for boundary layer resolution or in wake regions for flow separation analysis.

• T-Rex facilitates the creation of very thin, high-aspect-ratio cells in specific directions, which is crucial for accurately capturing phenomena like boundary layers in high-speed airflow analysis.
• This technology automates the extrusion process, reducing the manual effort typically associated with generating layered meshes around complex geometries, thereby accelerating the meshing workflow.
• It is particularly effective for composite flows where different mesh strategies may be required in distinct flow regions, allowing for a unified meshing approach.

Real-World Applications in Aerospace and Engineering

Fidelity Pointwise is a relied-upon tool in demanding engineering sectors due to its capacity for generating precise meshes for complex fluid dynamics problems. Its application is prevalent in scenarios where accurate simulation results are critical for design validation and performance prediction.

• Automotive: Applied to generate meshes for external aerodynamics of vehicles, internal engine components, and cooling systems to optimize performance and efficiency.
• Turbomachinery: Employed in the design of turbines and compressors by creating meshes for internal blade passages and flow paths to analyze performance and efficiency.
• General Engineering: Utilized in various fluid flow simulations, such as heat exchangers, HVAC systems, and environmental flows, where accurate geometric representation and mesh quality are essential.

Comparison with Other CFD Tools

While numerous software packages exist for CFD analysis, Fidelity Pointwise distinguishes itself primarily through its specialized focus on geometric modeling and advanced mesh generation. Many CFD suites incorporate meshing modules, but Pointwise often provides more control and specialized algorithms for creating high-fidelity meshes.

Compared to integrated CFD software that includes meshing as one component, Fidelity Pointwise offers a deeper specialization in the complexities of CFD mesh generation, particularly with its T-Rex technology for challenging boundary layer resolutions. This focus allows for greater automation and quality control in the meshing step, which can be a significant bottleneck in the overall CFD workflow.
