Ansys Platform Solutions

Proven Solver Technology

Multiphysics technology from Ansys is built on proven solver technology validated by many years of analyses by the world’s leading corporations and universities. Technical depth and breadth in all physics — structural mechanics, heat transfer, fluid flow and electromagnetics, even down to the chip level — is essential to understanding the complex interactions among different physics disciplines. This industry-leading solver technology for all physics disciplines, in conjunction with the engineered scalability of the Ansys product portfolio, enables users to solve challenging, real-world multiphysics problems.

Unified Simulation Platform

The Ansys Workbench platform is a powerful multi-domain simulation environment that harnesses the core physics from Ansys, enables physics interoperability and provides common tools for interfacing with CAD, repairing geometry, creating meshes and post-processing results. An innovative project schematic view ties together the entire simulation process, guiding the user through complex multiphysics analyses with drag-and-drop simplicity.

Powerful HPC Solver Capabilities

HPC is a strategic enabler for users who want to increase the value they derive from engineering simulation. It enables high-fidelity simulation (bigger, more detailed, more accurate, more complete systems-level simulation), which is critical for organizations that want to leverage simulation to support product innovation. As problem sizes and complexities increase with systems and multiphysics focus, best-in-class solver technologies from all physics disciplines must work together to solve the complete simulation.

Ansys HPC solutions enable you to increase the number of design variations you can compute in a given period, leading to better, more optimized products — which you can launch in the marketplace in a shorter time frame.

Design Exploration and Optimization Continuing core solver improvements across the Ansys suite remove scaling bottlenecks, pushing performance out to higher core counts and enabling efficient processing of numerically large, incredibly detailed simulations. Examples include architecture-aware partitioning (top), domain decomposition (middle) and distributed memory parallel processing (bottom)

Good design starts with identifying the relationship between performance and design variables. Ansys design exploration tools enable engineers to perform design of experiments (DOE) analyses, investigate response surfaces and analyze input constraints in pursuit of optimal design candidates.

Simulation Process and Data Management

The solution to managing complex processes and the resulting CAE data explosion is an end-to-end support system designed with a special focus on scale, scope and purpose. Ansys Engineering Knowledge Manager (EKM) supports the seamless sharing of product specifications, performance metrics and other critical engineering insights — so that the entire team, even when dispersed across multiple time zones and geographies, is equipped with the same reliable, real-time information at both component and system levels.

Native CAD Import and Robust MeshingA scalable solution, EKM supports single users and shared configurations with a flexible and simple licensing model. It allows for connections to local or remote repositories, encouraging CAE collaboration across dispersed teams.

Native, bidirectional CAD connectivity and automatic meshing with advanced options are provided through the Ansys Workbench platform. This environment connects with major CAD systems and allows import from most neutral geometry formats.

Ansys Workbench also provides a wide range of highly robust and automated physics-based meshing tools, including tetrahedral, pure hexahedral, mixed hex/tet/pyramid, inflation layers and high-quality surface meshes. Users have the ability to control many advanced meshing options such as body, surface or edge sizing controls, sphere of influence, inflation layer meshing, mesh defeaturing tolerances, and much more.

Seamless Data TransferAutomated CFD meshing includes inflation layers for complicated geometries, such as this drill bit model.

Best practices for meshing depends on the physics being examined.  Good meshes for structural analysis are not the same as for CFD.  At the same time, the mechanical engineers may not be knowledgeable in CFD, or electrical engineers may not be versed in structural analysis. Data can be simply shared among engineers in the form of text files defining point clouds but transferring this data to the mesh for another physics is a painful process without the right tools. The Ansys Workbench platform allows a seamless data transfer from one physics area to another, and it automates the mapping between dissimilar meshes. Workbench easily imports data from external sources, such as point clouds, and transfers them onto your current structure. You can modify scaling, units and orientations to match the point cloud data to your model. Visual quality controls check the accuracy of the transferred data.
