What’s New in Simcenter 3D? Simulating Turbomachinery, Drop Tests, and More

Creating accurate complex turbomachinery design simulations is easier than ever with the latest release of Simcenter 3D. 

Simcenter 3D is a comprehensive simulation tool that can help design engineers and analysts solve challenging multi-disciplinary engineering problems. The solution offers manufacturers better insight into a product’s overall performance.  It is integrated with Siemens NX, but can also function as a standalone solution. Simcenter 3D’s latest release introduces a rich set of capabilities that improve the simulation experience for engineers.

Develop Complex Products Using Simcenter 3D

The products engineers are developing are only becoming more complex. They must lean into that complexity if they are to succeed. Using simulation software early in the design process helps engineers tackle the challenge. 

Simcenter users perform several complex simulations during product development. They  need a solution that does not slow the design process down. Simcenter 3D users typically use Siemens CAD solutions, so they also care  about integrating CAD with simulation to improve workflow efficiency. 

Siemens addresses many of these potential concerns in the latest release of Simcenter 3D, which empowers users to better develop complex products. In this post, we examine how Simcenter 3D’s latest release can:

  • push the simulation boundary for turbomachinery design,
  • extend simulation capabilities, and
  • improve simulation management and collaboration.

Turbomachinery Analysis

Designing turbomachinery is challenging. Engineers have to consider structural, fluid flow, vibration, and thermal phenomena. Simcenter 3D enables engineers to handle all these design considerations within the same simulation environment, and its latest release has many improvements related to turbomachinery simulation. 

Multi-stage Analysis – Turbomachines are typically analyzed using cyclic symmetry. These complicated machines have multiple stages, however, and the connection between stages is critical to achieving accurate simulation results. In the past, turbomachinery simulation has struggled to model this connection. Simcenter 3D’s new release includes tools that allow users to accurately handle turbomachines with interstage junctions. Higher-order harmonics are automatically added to the simulation. Turbomachinery designers can visualize results in any particular stage or recombine results on a full 3D model.

Heat Transfer – Studying thermo-mechanical behavior is critical to turbomachinery design. Engineers need accurate heat transfer coefficients to fully understand this phenomenon, but extracting heat coefficients typically requires full 3D computational fluid dynamics (CFD) analysis. And while this simulation method is the holy grail of turbomachinery simulation experts, they rarely use it due to the cost and time involved in calculations. The new release of Simcenter 3D can perform partial 3D CFD simulations, which can then be integrated with axis-symmetric simulations. This solution gives engineers accurate heat transfer coefficient values, saving time without compromising accuracy.

Thermal Fatigue – Thermal fatigue is a common reason why turbomachines fail. In-house simulation is commonly used to predict thermal fatigue, but it’s not a perfect solution. These simulations are manually intensive, and manufacturers struggle to obtain accurate material curves. To compensate for these weaknesses, engineers often over-design turbomachines. More material may be added to prevent thermal fatigue, which compromises weight and adds unnecessary costs. 

Simcenter 3D introduces a time-varying thermal fatigue solution that can solve this problem. Users can perform a temperature-dependent fatigue analysis that allows engineers to study the durability of their design and optimize for thermal fatigue.  

Drop Tests without a PhD

Consumers are bound to drop small electronic devices, such as smartphones or digital cameras. Those same consumers expect their products to continue to function normally after they drop them. Engineers want to ensure that products work after they are dropped, and small consumer electronics manufacturers want to predict warranty claims. Drop tests allow manufacturers to understand how their devices perform when inadvertently dropped. Simulating drop tests typically requires a high level of expertise in structural engineering. 

Simcenter 3D now has a complete, dedicated drop test solution that helps engineers set up, simulate, and create reports for drop tests. Simulating drop tests no longer requires proficiency in structural engineering.

Residual Stress and Composite Laminates

Accurately modeling material properties is critical in any simulation. Simulation software must include material behavior along with the correct property values. To compound this complexity, the rise of additive manufacturing has introduced many new engineering materials. Simcenter 3D offers many new material engineering capabilities. These capabilities ensure engineers can accurately model product properties, such as residual stress. 

Residual stress can be difficult to predict in components manufactured using additive processes. This stress impacts the mechanical integrity of the finished product. Understanding the residual stress distribution is helpful in additive manufacturing design. Simcenter 3D allows engineers to accurately predict residual stresses in these components. 

Ease of use was the main issue with simulation software in the past. Since compost laminates are increasingly popular in today’s products, engineers need a simulation solution that works intuitively and effectively. Simcenter 3D has made the workflow easier and intuitive so that all engineers—not just experts—can analyze products made from composites.

Remote Simulation and Collaboration

Using remote machines to solve time-consuming simulations is more vital than ever. Simcenter 3D offers capabilities for remote simulation and collaboration. Running complex simulations can make devices nearly inoperable for long periods of time, but engineers want to continue using their computers while simulations are running. Remote machines allow engineers to focus on other design duties while simulation occurs.

Users can now run remote simulations in Simcenter 3D, freeing up computer resources. Users can launch simulations on any network-connected workstation running Windows or Linux, and monitor progress using any web browser. Manufacturers may want to invest in machines that are dedicated to running simulations, as this benefits engineers while speeding up design processes. 

Engineers no longer design products in a silo. The modern product development process involves many stakeholders. External stakeholders, such as contractors, consultants, and regulators, are critical to the success of new product development projects. Xcelerator share is now available for Simcenter 3D, making it easier than ever to share simulations with those external stakeholders. Users can share simulation models and results over the cloud with their collaborators. 

Improve Simulation with Simcenter 3D

Simulating product performance before the design is finalized improves the entire product design process. In the past, design engineers often struggled to find easy to use simulation products that met their design needs, leading to the over-design of products. Thanks to cutting-edge simulation software, manufacturers can now create better product designs.

Simcenter 3D enables users to accurately simulate complex product performance. Partial 3D CFD analysis provides insight into thermo-mechanical behavior, and engineers can model thermal fatigue to prevent product over-design. Electronic device manufacturers can accurately predict how dropped products will perform, and Simcenter 3D’s material engineering simulations give engineers insight into material performance. Finally, Xcelerator share simplifies collaboration. Simcenter 3D is a robust product simulation tool with ample benefits for manufacturers.
