AnalySwift’s Release Latest VABS Software

24 January 2012

AnalySwift has released VABS 3.6 featuring an improved method of optimising the finite element mesh.

According to AnalySwift, VABS 3.6 is several times faster for large problems compared to the previous version, and the slower I/O (Input/Output) performance reported by some users was corrected. They say VABS 3.6 can handle much larger models, which cannot be analyzed by previous versions.

According to Dr. Wenbin Yu, CTO of AnalySwift, “For a realistic blade meshed with 200,000 degrees of freedom (DOFs), using a typical laptop, VABS 3.6 takes less than 20 seconds for constitutive modelling (Timoshenko model), while VABS 3.5 takes about 4 minutes for constitutive modelling. Of course, if one uses DLLs (Dynamic Link Libraries), it will be even faster as a significant portion of time for large problems is spend by I/O with hard drives.”

“We are excited for the time and cost saving benefits this version of VABS provides both industrial and academic users of VABS,” said Allan Wood, President and CEO of AnalySwift. “While VABS is already known for its efficiency in realistic multiphysics blade modelling, this version is even more appealing by truly taking it to the next level.”

According to Yu, “VABS is the only tool capable of rigorously modelling three-dimensional (3D) slender solids with complex buildup structures, such as composite wind turbine blades.” Wenbin continued, “The efficient high-fidelity tools offered through AnalySwift enable companies to bring products to market more quickly and at a lower cost with the best available compromise of accuracy, efficiency, and versatility.”

 AnalySwift say that the technology underlying VABS renders it an efficient high-fidelity modelling tool for composite beams, saving users many orders of magnitude in computing time relative to more complex and time-consuming 3D finite element analyses (FEA), without a loss of accuracy. They continue to explain that engineers can design and analyse real structures with complex internal construction due to the high-fidelity feature of VABS.
