Take the guesswork out of your decision making. Move confidently forward using Arena software. Simulation software is the creation of a digital twin using historical data and vetted against your system’s actual results. Arena™ Simulation Software uses the discrete event method for most simulation efforts, but you will see in using the tool that we cover areas in flow and agent-based modeling as well. Evaluate potential alternatives to determine the best approach to optimizing performance. Understand system performance based on key metrics such as costs, throughput, cycle times, equipment utilization and resource availability. Reduce risk through rigorous simulation and testing of process changes before committing significant capital or resource expenditures. Determine the impact of uncertainty and variability on system performance. Run "what-if" scenarios to evaluate proposed process changes.

VABS is a popular general-purpose cross-sectional analysis tool for quickly and easily computing beam properties and recovering 3D fields of composite beams, including helicopter and wind turbine blades. It is the only tool capable of rigorously decoupling an original 3D slender solid with complex microstructure into a simple engineering beam model. AnalySwift’s roots are in the aerospace industry, where its tools have been used for composite beams (helicopter rotor blades, propellers, high aspect ratio wings, wing section design), plates/shells, and 3D structures. Used for several years in the wind turbine industry, VABS delivers rapid, rigorous results when modeling wind turbine blades. SwiftComp provides additional solutions for plates/shells, and 3D structures manufactured from composites. As the automobile industry adopts a higher use of composites, opportunities increase to leverage SwiftComp and VABS to model a wide variety of structures, including beams, plates, shells, etc.
