AcuDesktop™ is an industrial strength, general-purpose, desktop based Computational Fluid Dynamics (CFD) software developed by ACUSIM Software, Inc., the developer of leading commercial finite element-based CFD solver technology and solutions. With superior robustness, speed and accuracy, AcuDesktop offers complete CFD capabilities from pre-processing, solver solutions, to post-processing in an easy to use, single integrated software environment. AcuDesktop enables mainstream CAE engineers and designers with a powerful CFD tool that is cost effective and easily accessible from their desktops.

Advanced Solver TechnologyAcuDesktop typically solves a given problem in the first attempt. Fully converged solutions are reliably obtained using AcuDesktop’s efficient steady-state solver. Nonlinear convergence remains strong even as solutions approach their final result. Two key components contribute to this robustness and speed: (1) the Galerkin/Least-Square (GLS) finite element formulation; and (2) a novel iterative linear equation solver for the fully coupled pressure/velocity equation system. GLS is a higher-order accurate, yet stable formulation, with a well-established mathematical foundation. The linear solver yields significant stability and convergence advantages over the segregated solution procedures commonly found in many commercial incompressible flow solvers.

AcuDesktop™ A Powerful General-Purpose CFD Solution for Desktop Users

Powerful and Easy Pre-Processing ModelingAcuDesktop comes with a powerful, easy to use GUI-based pre-processor. It can work with very complex geometries, build simulations from CAD or Mesh and import 3D CAD models from ProE, Parasolid, ACIS, Discrete, Catia V5, or import an existing mesh in various formats. AcuDesktop has a built-in automatic mesh generator with boundary layers and is capable of efficiently solving unstructured meshes with high aspect ratios and badly distorted elements commonly produced by fully automatic mesh generators on complex industrial geometries. These capabilities enable highly accurate results in greatly reduced solution times.

Industrial-Strength Post-Processing CapabilitiesAcuDesktop also comes with an industrial-strength post-processor, an OEM-bundled version of FieldView from Intelligent Light. FieldView is one of the most widely used and powerful post-processors in the CFD industry. AcuDesktop users can now interrogate and visualize complex flow simulations without leaving the ACUSIM product environment.
