Optimize Your Engineering Workflow with CADfix: Advanced Meshing Solutions for CAD Repair, STL, and CAE Applications
CADfix offers comprehensive meshing solutions designed to address common challenges in Computer-Aided Design (CAD) and streamline the preparation of models for simulation and analysis. Built upon a flexible and tolerant geometry kernel, CADfix provides robust tools for CAD repair, defeaturing, and mesh generation, ensuring seamless integration into various engineering workflows.
CAD Challenges and Solutions
In many engineering processes, CAD models present issues such as geometric imperfections, unnecessary features, and complexities that hinder efficient meshing and analysis. CADfix tackles these challenges by offering:
- CAD Repair and Defeaturing: Automatic correction of topological problems to create solid models, simplification of geometry by removing holes, protrusions, fillets, chamfers, and midsurfacing.
- Flexible Geometry Kernel: A robust platform tolerant of common CAD defects, facilitating seamless model transformation and preparation for meshing.
STL Meshing for Visualization and Simulation
STL meshing is vital for applications ranging from visualization to simulation. CADfix provides advanced STL meshing capabilities, including:
- Surface Meshing: Generation of high-quality meshes suitable for visualization and augmented/virtual reality (AR/VR) applications.
- Geometry Proxy Creation: Production of proxy geometries compatible with tools like snappyHexMesh, Converge CFD, and GridPro.
- Format Versatility: While STL is common, CADfix supports multiple output formats to meet diverse requirements.
CAE Meshing for Advanced Analysis
For CAE, CADfix offers robust meshing solutions:
- Linear and Quadratic Tet Meshing: Generation of high-quality tet meshes with options for linear and quadratic elements.
- Hexahedral Meshing: Advanced tools for creating structured hexahedral meshes, enhancing simulation accuracy and efficiency.
Mesh Sizing and Control
Precise control over mesh sizing is crucial for accurate simulations. CADfix provides:
- Geometry-Based Sizing: Utilization of parameters like sag (maximum element-to-geometry distance) and turn (maximum surface normal change across elements) for mesh refinement.
- Automatic Defeaturing: Removal of insignificant features such as short edges and slivers to optimize mesh quality.
- Thin Region Sizing: Ensuring adequate element distribution across thin sections for accurate analysis.
Hex Meshing Capabilities
CADfix excels in generating high-quality hexahedral meshes through:
- Body Splitting Using 3D Medial Axis: Efficient subdivision of complex geometries to facilitate structured meshing.
- Face Splitting with Cross-Field Techniques: Advanced methods for creating well-structured mesh faces.
- Dynamic Splitting Tools: Manual construction of splitting geometry for customized meshing strategies.
- Recipe-Based Hex Meshing: Smart sizing and balancing through customizable meshing recipes.
