Discover the latest advancements in Ansys Discovery 2025R2, focusing on critical upgrades for Computational Fluid Dynamics (CFD) Simulation.

Thermal Management: Internal 3D Fans

The 2025 releases of Ansys Discovery continues improvements in thermal management, particularly with the introduction of internal 3D fans. These enhancements allow for more accurate modeling of real-world thermal behavior, crucial for electronics cooling. Users can now add fans to cylindrical or rectangular fluid regions, simulating internal airflow with fan performance curves or constant pressure rise to reflect real-world conditions.

A built-in fan library with common electronics cooling fans facilitates faster setup, supporting both shrouded and unshrouded configurations. This addition improves the accuracy of simulations by including real-world fan behavior, essential for applications where fans are internal to the flow domain. Additionally, the software monitors pressure rise and flow rate, enabling precise tracking of fan performance.

 

New Fluid Mesh Capabilities

Ansys Discovery 2025R2 also brings enhanced fluid meshing capabilities that elevate the precision of simulations.

Body of Influence Local Fidelity for Fluids (Explore)

One of the key features is the Body of Influence (BOI) local fidelity,  supported on suppressive geometry,  which allows for flexible local mesh control. This feature enables flexible BOI placement, fully or partially overlapping fluid or solid regions of any shape. It is different from Workbench BOI, which is like a sphere or a box.

 

Sharp Edge Capture (Explore)

The sharp edge capture feature improves mesh resolution at inlets, outlets, and well-defined fluid boundaries. In previous versions, a lack of sharp-edge capturing led to unwanted smoothing and rounding at inlet and outlet holes and flange edges which resulting in geometry errors that compromised simulation accuracy. With the introduction of sharp edge capture, mesh fidelity around these critical regions is greatly enhanced, providing more accurate area calculations. This improvement directly supports more reliable predictions of performance monitors such as mass flow rate and pressure drop at entry and exit points in the fluid domain, thereby ensuring that simulation results closely align with actual system behaviors. 

 

 

Some additional features in Ansys Discovery 2025R2

  • Fully Developed Velocity Inlet Profiles: This capability is now available in both Explore and Refined modes,  supporting circular inlets only but accommodating both laminar and turbulent velocity profiles. With this advancement, there is no longer a need to artificially extend the flow domain to achieve fully developed flow, resulting in a more efficient computational setup and a reduced problem size.

  • Heat Flow Monitoring: The introduction of heat flow monitors at inlets, outlets, and wall boundaries enhances the capability to accurately assess heat balance in fluid-thermal and conjugate heat transfer analyses. This feature provides improved thermal performance evaluation and greater confidence in simulation outcomes.
  • Monitor Details Saved in Project: Simulation monitors created during analysis are now preserved within the project file. When reopening a saved project, all configured monitors are readily accessible, enabling thorough review of solution convergence and transient response in subsequent sessions. This enhancement streamlines post-processing and supports more effective evaluation of simulation accuracy.

  • Bidirectional Streamlines: This new feature allows users to visualize the entire trajectory of fluid particles as they travel through emitters positioned within the fluid domain. It offers a detailed understanding of complex flow structures, the impact of boundary conditions, and interactions with obstacles inside the flow. By utilizing bidirectional streamlines, we can effectively illustrate the flow field around an object, including the wake formation downstream, enhancing our insights into the fluid dynamics at play. 
     

  • Transfer of Heat Transfer Coefficient (HTC) and Temperature to Ansys Mechanical: Users can now seamlessly link conjugate heat transfer simulations in Discovery to subsequent thermal or thermal-stress analyses in Ansys Mechanical. This integration provides accurate, spatially resolved HTC values and fluid temperature data at the fluid-solid interface, significantly improving the fidelity of thermal and thermal-stress predictions within Mechanical and ensuring consistency across simulation domains.

 

 

AI-Powered Copilot

The Ansys Discovery 2025R2 introduces an AI-powered Copilot that enhances user experience and performance. Integrated within the Discovery interface, it provides contextual support for simulations and modeling. Leveraging 50 years of Ansys expertise, the Copilot offers in-product guidance, access to learning resources, and integration with AnsysGPT and technical support. This innovation accelerates troubleshooting and minimizes reliance on external searches, allowing users to quickly find needed information for a more efficient and supportive simulation experience.

 

 

New Features Benefits

These enhancements provide additional user flexibility for controlling mesh density, thereby improving simulation accuracy and optimizing the use of GPU memory for complex fluid and thermal applications. The software also includes new fluid simulation options, heat flow monitors, and the ability to transfer heat transfer coefficients and temperatures to Mechanical simulations, further enhancing the simulation's fidelity. The AI-Powered Copilot further elevates the experience by providing contextual, expert guidance throughout the CFD workflow, ensuring improved usability and performance with Discovery 2025R2.
