Ansys is designed to simulate the interaction among structural mechanics, heat transfer, fluid flow and electromagnetics, from one-way data transfer and mapping methods that “glue” physics together, to full two-way multiphysics coupling for complex interactions.

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, geometry repair, mesh creation 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

High Performance Computing (HPC) enables high-fidelity multiphysics simulation (bigger, more-detailed, more-accurate, more-complete systems-level simulation)  as problem sizes and complexities increase. Continual 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.

Native CAD Import & Robust Meshing

Ansys Workbench has automated, easy-to-use solutions to simulate fluid-structure interaction (FSI) problems accurately and efficiently.

Modeling approaches can vary depending on the level of FSI occurring, but Ansys Workbench has solutions for both one-way and two-way coupling. A simple drag-and-drop task will directly link your CFD and FEA analysis to transfer and map loads for one-way coupling. One-way coupling simulations can easily be transformed into two-way coupling using the System Coupling component with the same drag and drop approach.

Ansys Meshing features
Automated CFD meshing includes inflation layers for complicated geometries, such as this drill bit model

Seamless Data Transfer

Best practices for meshing and model set-up depends on the physics being examined and domain knowledge  may need to be shared between engineers or even departments when undertaking multiphysics simulations. The ANSYS Workbench platform allows a seamless data transfer from one physics area to another, and it automates the mapping between dissimilar meshes.
