“I was amazed at how significant AcuSolve’s speed could be. I can barrel through 40 design files with four or five components per design in a week, whereas with our old software it would have taken a month. With AcuSolve’s accuracy, we now have a lot of confidence in our predictive capabilities.”
–Tom Lincoln, CAE Engineer

Altair offers three powerful solutions to meet your CFD meshing and modeling needs. AcuConsole™ was designed exclusively for interoperability with AcuSolve and provides a great solution for organizations with an analysis process that relies on watertight 3D-CAD models. It provides full AcuSolve model set up capabilities, plus fast and efficient CFD meshing. The AcuConsole work flow provides extensive abstract modeling capabilities through the use of templates that record mesh and model settings independent of the CAD model. Design studies are performed quickly and easily by simply importing the modified CAD model. All model specific settings are automatically assigned to the corresponding faces of the new geometry. This capability prevents you from having to constantly perform the same model set up steps over and over again as the CAD model is updated throughout your design process.
If CAD clean-up and multi solver support is a necessity for your organization, then HyperMesh fulfills your CFD preprocessing requirements. HyperMesh's reputable geometry clean-up features now come equipped with a full suite of tools for CFD meshing and model set-up. Automated tools can fill holes and gaps between parts and wrapping techniques can create exterior watertight meshes or cavity meshes for the interior. Mesh controls for the entire model and individual features can be defined and saved for use in subsequent models, guaranteeing repeatability of results. When combined with an interface to most major CFD codes, HyperMesh proves to be a formidable player in the CAE marketplace, providing an all in one solution for both CFD and structural modeling needs.
If your organization desires a fully automated simulation based design process, then AcuNexus is the right tool for you. AcuNexus is a preprocessor specifically developed for AcuSolve models and is provided through the Altair Partner Alliance. AcuNexus relieves CFD analysts from non-value added tasks and significantly accelerates product innovation through its CAD based abstract modeling methodology.
CFD Optimization with HyperWorks
HyperMesh’s morphing technology, HyperMorph, enables you to quickly generate new shape variables to explore designs. The coupling of morphing, HyperStudy and the CFD solver of your choice allows you to run different study types in an automated manner to improve the performance of your design. The extensive read/write interfaces for commonly used CFD solvers (e.g. AcuSolve, StarCD, Fluent, CFD++, and SC/Tetra) make the optimization process run smoothly.
HyperStudy supports shape optimization, Design of Experiments (DOE), and stochastic studies. HyperStudy allows combined fluid-structure optimization by managing both CFD and structural FEA analyses, combining the results to solve your toughest Multi-Disciplinary Optimization (MDO) problems.
HyperWorks is the premier tool for CFD optimization and MDO problems.
CFD Post Processing
AcuFieldView is an OEM version of Intelligent Light's FieldView CFD post-processor, and has the ability to manage large and complex CFD data visualization requirements. It incorporates Intelligent Light’s most recent advancements in FieldView, including a new codebase that produces optimized graphics performance and a single, easy to use graphical user interface (GUI) on all platforms. AcuFieldView provides full CFD post-processing functionality, but only functions with results generated by AcuSolve. If your CFD process involves results from multiple solvers, then post-processing with HyperView is the right solution for you. In addition to having the familiar HyperWorks user experience, HyperView can import result data from all major CFD solvers (AcuSolve, CFD++, FLUENT) via the EnSight format. The data can be visualized interactively or in an automated manner to standardize the reporting process.
Built upon a rigorous scientific foundation, AcuSolve is a proven asset for companies looking to explore their designs by analyzing fluid flow. AcuSolve provides a full range of analysis capabilities without the drawbacks and difficulties associated with traditional CFD applications.
Experienced CFD analysts are all too familiar with the challenges of getting a simulation to run in the majority of commercial solvers. Endless geometry simplification to construct block structured meshes, days spent wrestling with meshing software, and solution divergence due to poor quality meshes are common issues faced in the workflow of many solvers.
AcuSolve provides you with the tools you need to avoid the CFD pre-processing bottle neck and focus on exploring your CFD simulation results. AcuSolve's powerful solver technology provides you with the most robust solution in the CFD marketplace. AcuSolve's numerical methods yield stable simulations and accurate results regardless of the quality and topology of the mesh elements. When combined with automated unstructured meshing, no CFD software gets you to the end goal sooner! Analyzing results and exploring the physics of your application, AcuSolve achieves all of this without the need to perform countless runs to explore different solution procedures. AcuSolve's single solver architecture and constantly evolving feature set provides a valuable tool to any company tasked with performing CFD analysis. No solver tuning required: Build your mesh and run it!
