Computer-aided engineering (CAE) helps to analyze mechanical designs and define its bottlenecks. Without physical prototyping, it can simulate stress and vibration, thermal and electromagnetic environment impact, fluid flow behavior, or interconnected parts dynamic operation. However, it is sometimes a challenge to consistently transfer data between design and analysis tools.
Look how CAD Exchanger SDK solves the problems of geometry import from CAD and subsequent meshing for the following CAE applications.
CFturbo GmbH is engaged in turbomachinery design and engineering services. Its conceptual software is used to create and optimize axial, mixed-flow, and centrifugal systems: pumps, fans, blowers, ventilators, compressors, and turbines.
Among other things, CFturbo allows engineers to export models to the downstream CAD and CAE software. CAD Exchanger SDK and Netgen mesher duet enables volume meshes generation and communication with a wider range of software (Netgen, Abaqus, Fluent, OpenFOAM). More details on this collaboration are here.
Concepts NREC develops and distributes turbomachinery solutions for over 60 years. The company is an expert in related engineering services, CAE /CAM software, manufacturing, testing, and training. Its software covers the entire design process from preliminary sizing through detailed 3D geometry, from fluid dynamics through machining toolpaths.
CTAADS is a part of a specialized design lineup providing 3D modeling features for axial gas turbine blades and vanes cooling. CAD Exchanger SDK enables data transfer: import of an airfoil shape and export of a finite element model to the third-party CAD tool.
AxCent is another remarkable product of Concepts NREC. It deals with a 3D geometric design of radial, axial and mixed-flow compressors, fanes, pumps, and turbines.
CAD Exchanger integration ensured AxCent compatibility with external CAD packages with IGES and STEP support.
SHIPFLOW® by FLOWTECH International AB
FLOWTECH International AB is a leading CFD solution for ship design. Its flagship software SHIPFLOW serves for hydrodynamic analysis and optimization of hull form, energy-saving devices, resistance and propulsion, flow and wake, seakeeping and added resistance in waves.
CAD Exchanger SDK was integrated to support complex vessels' geometry import from CAD systems to SHIPFLOW. IGES hull designs now may undergo CFD analysis, while automatic tessellation increases its performance. To know more about this SDK integration, read this success story.
CAD Exchanger is able to generate computational meshes that fit FEA and CFD calculations without missing or deformed parts. It includes the following features for CAE systems:
- Support of various CAE formats and numerous 3D modeling kernels
- Generation of surface (2D) and volume (3D) meshes from precise B-Rep
- From triangles and arbitrary polygons to define the surface through tetrahedrons and pyramids to fill the internal space
- Customizable settings to get the mesh meeting your specific requirements
- Specifying boundary conditions
- Support of multiple LODs (Level of Details)
- Cross-platform approach: WebGL/three.js, Qt/Quick, C#/WPF, etc.
