VABS-IDE
(VABS-enabled Integrated Design Environment)

We occasionally receive inquiries about a tool called VABS-IDE or VABS-enabled Integrated Design Environment.

There are no companies authorized to distribute legitimate copies of VABS-IDE. VABS-IDE was a program utilizing an early version of VABS in a design environment, but VABS-IDE was never licensed for distribution or sale.  AnalySwift, LLC, is the exclusive license-holder of the VABS software, and the only authorized distributor of VABS or VABS-derived software developed by Utah State University and Georgia Institute of Technology.  Sale, distribution, or use of VABS-IDE constitutes violation of the VABS copyright held by Utah State University and Georgia Institute of Technology.  If you have any questions about VABS-IDE, please contact AnalySwift or Utah State University.

If you are interested in evaluating the latest and most accurate version of VABS, please request a free trial below. With continuous development spanning over 20 years for performance and robustness, VABS is used in the aerospace and wind energy industries for modeling complex composite rotor blades, wing section design, and simulating other slender structures. VABS can accurately compute the complete set of beam sectional properties for slender structures featuring arbitrary cross-sectional shape and materials. It can reproduce the accuracy of direct numerical simulation using 3D FEA by explicitly modeling all the ply details of composite beams. VABS directly interfaces with ANSYS, ABAQUS, and others.

How can VABS help you?

  • Unprecedented competitiveness through efficient, accurate modeling of real composite beams and other slender structures.
  • Drastically reduced design cycle and time-to-market by saving orders of magnitude in design and analysis time.
  • High fidelity results on a typical laptop computer, instead of a prohibitive detailed 3D FEA (even with heavy computing power).
  • An enabling technology for nonlinear aeroelastic analysis of highly flexible structures.

VABS Applications

MULTISCALE MODELING OF COMPOSITE BEAMS

  • Helicopter rotor blades
  • Wind turbine blades
  • Propellers
  • High-aspect ratio wings
  • Golf clubs
  • Fishing rods
  • Other slender composite structures

VIRTUAL TESTING OF COMPOSITE BEAMS

  • Complete set of best multiphysical properties: needed for static/dynamic analysis using beam elements.
  • Complete set of accurate multiphysical 3D fields: analyze under coupled effects of thermal, mechanical, and electromagnetic fields.
  • Material properties: no restrictions on material properties and can handle any material, including isotropic, orthotropic, and anisotropic materials.
  • Highly optimized for efficiency: ply-level details of real blades can be modeled in seconds.
  • Directly integrated into other design environments, including ANSYS, ABAQUS, and CATIA.
  • Reap the full benefits of VABS using free companion code GEBT (1D beam analysis), which accepts the full stiffness matrix. PostGEBT, a postprocessor to GEBT is also available.

Unique Technology

VABS is a proven technology for an efficient alternative to detailed 3D FEA for composite beams. It is the only tool capable of rigorously decoupling an original 3D slender solid with complex microstructure (sophisticated cross section with or without spanwise heterogeneity) into a simple engineering beam model. As long as beam elements are used in the design (such as multibody dynamics simulation, aeroelastic simulation), VABS will compute the best stiffness constant (such as torsional stiffness) for the beam element. To deal with a composite wing/rotor, many 3D FEA rely on smearing many layers into one thick layer, which introduces significant errors and defeats the very purpose of being high fidelity. However, VABS can compute ply-level stress field without such approximations (achieving the accuracy as if 3D FEA models all the ply level details).
