SwiftComp by AnalySwift

SwiftComp is a groundbreaking software for modeling composite materials with exceptional efficiency and accuracy. It bridges the gap between microscopic material behavior and macroscopic structural performance. Unlike traditional methods, it allows engineers to model composites as easily as metals within existing FEA software. This one-stop solution offers multiscale modeling for various structures (beams, plates, 3D) while capturing intricate details. Use SwiftComp independently or as a plug-in for existing tools (it directly interfaces with ANSYS Workbench & Classical), making it highly versatile for diverse applications. SwiftComp surpasses typical RVE analysis by delivering 3D properties and local fields more efficiently using lower dimensional domains and fewer calculations. It revolutionizes composite simulations by seamlessly connecting microstructural details with overall structural behavior.

VABS by AnalySwift

VABS is a general-purpose, cross-sectional analysis tool specifically designed for the cost-effective modeling and simulation of complex composite materials such as composite rotor blades, tubes, and other slender composite structures. It allows engineers to analyze these composite structures with unmatched detail and efficiency. The latest version of VABS blade modeling software offers additional capabilities, including calculating the strength and safety of cross sections under given loads. Besides helicopter and wind turbine rotor blades, VABS has more recently proved to be popular for growing applications in air mobility (AAM, UAM, eVTOL, etc.). Originally developed to address the challenge of quickly and accurately modeling complex helicopter rotor blades, the VABS software rapidly found applications helping engineers in a wide variety of industries. Also used today for wind turbines, urban air mobility, landing gear, industrial tubes, golf clubs, and fishing rods, VABS provides engineers with an even better understanding of the products they are designing or analyzing.

Key Features

  • Cross-Sectional Analysis for Slender Structures: VABS focuses on analyzing the cross-section of slender structures, particularly those featuring complex materials like composites.
  • Accurate Beam Property Calculations: It delivers highly accurate calculations for a complete set of beam properties, crucial for structural analysis.
  • Recovers 3D Stresses and Strains: VABS goes beyond basic properties, allowing recovery of 3D stress and strain data within the composite beam.
  • Explicit Ply Details Modeling: VABS explicitly models all the details of individual plies (layers) within the composite material, leading to more precise simulations.
  • Matches Accuracy of 3D FEA with Efficiency: VABS achieves the same level of accuracy as complex 3D Finite Element Analysis (FEA) simulations, but with significantly higher efficiency.
  • Ideal for Design Optimization: With its efficient and accurate analysis, VABS is well-suited for optimizing the design of composite beams.
  • Suitable for Various Composite Structures: VABS can handle a broad range of composite structures, including helicopter and wind turbine rotor blades, propellers, landing gear, and more.
