"SwiftComp™ and VABS™ enable ANSYS to simulate composites and other advanced materials with an unprecedented combination of accuracy and efficiency (think seconds not hours). Users can consider more design options and arrive at the best solution faster, as well as handle more complex problems, so the company can get to market more quickly while reducing costs.
- SwiftComp is a general-purpose multiscale modeling code that enables users to perform efficient and accurate modeling of composites. It can be used as a plugin to power high-fidelity multiscale modeling for composites. SwiftComp provides unified modeling for various types of structures including 1D (beams), 2D (plates/shells), woven, and 3D structures, directly and seamlessly linking micromechanics and structural analysis. It saves hours in computing time and resources with accuracy comparable to modeling all the microstructural details using 3D FEA. SwiftComp quickly calculates the complete set of effective properties needed for use in macroscopic structural analysis. It can also predict accurate local stresses and strains in the microstructure for the purpose of predicting strengths, as well as thermal expansion of composites. SwiftComp also has initial failure analysis capabilities, including predicting pointwise failure strengths distributions, failure envelopes, and effective failure strength for the composite.
- VABS is a general-purpose cross-sectional analysis tool for computing beam properties and recovering 3D stresses/strains of slender composite structures. It is a powerful tool for modeling composite helicopter and wind turbine rotor blades, as well as other slender composite structures, such as propellers, landing gear, and high-aspect ratio wings. VABS can calculate ply-level details with the accuracy of 3D FEA in seconds on a typical laptop computer. VABS is capable of rigorously reducing an original 3D slender solid with complex cross-sections into a simple engineering beam model. With continuous development funded by the US Army spanning nearly 30 years for performance and robustness, VABS' accuracy has been extensively verified by its developers and users.
