Learn how to make thermal simulation in the earliest stages of the design project
What is the role of CFD Software in our new world, with new rules, where businesses and consumers are always demanding more?
CFD Software turns complexity into a competitive advantage
People are looking for a better future with more personalized and safer products, reduced emissions, waste and materials usage, improved energy efficiency, and operational performance. Technological evolutions drive product innovation, bringing an explosion of complexity to meet these expectations.
One of the biggest challenges that engineers face today: there is an explosion of complexity while at the same time the pace of innovation is faster than ever. Avoiding complexity is not an option, so you must turn that complexity into a competitive advantage!
CFD software allows you to tackle complexity and be in the best position to drive innovation faster than your competitors.
How CFD Software works
CFD stands for Computational Fluid Dynamics, a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. CFD is applied to a wide range of research, studies, and industries, including aerospace aerodynamics and analysis, weather simulation, natural sciences, and environmental engineering, industrial systems design and analysis, biological engineering, fluid flow, and heat transfer, and engine and combustion analysis. This discipline gives its best with Frontloading CFD.
Frontloading means the use of simulation inside the 3D CAD environment allowing design and analysis to remain synchronized. It enables the rapid assessment of design changes by the designer himself, minimizing expensive late design changes.
As summarized in the chart below, the traditional process for doing CFD involves creating geometry in CAD, exporting it to a meshing tool, meshing it, setting up and running a CFD solver, post-processing results, going back into the geometry, altering it, and continuing to do these design loops again and again. A variant Siemens has pioneered over the years is the “frontloading” of CFD by embedding CFD technology inside CAD and PLM engines and workflows. This can compress the overall elapsed time to results by an order of magnitude.
CFD Software in practice
The Simcenter Portfolio
The Simcenter portfolio by Siemens is a set of state-of-the-art CFD solutions based on simulation as a fast and low-cost approach to accelerate product innovation. It enables you to take action in the four key areas for success:
1. Model the complexity
CFD Software allows you to model the complexity from material behavior to performance of entire systems. This includes coverage for a broad range of physics including structures, flow, electromagnetics, motion, thermal, and much more.
With Geometric Fidelity, you can stay true to your designs across all your simulations:
- Capture all the necessary details from component to system
- Get appropriate precision for every stage of the design cycle
- Increase consistency by working directly on your CAD
With Multiphysics CFD, you can simulate reality, no matter how complex the application:
- Get accurate flow solutions for all your applications in one place
- Model the right physics at the right time for the right application
- Keep your physics fully integrated into one simulation
2. Explore the possibilities
Equally important to giving our customers the ability to model complexity is enabling them to leverage these models to find trade-offs in design. The fact is – single point simulations are a thing of the past – today, simulation engineers want to run100s of simulations at once to get the necessary insight to deliver better products.
With Early CFD, you can make design choices when they have the most impact:
- Make critical decisions earlier in the design process
- Build simulations that grow with your design
- Expand CFD usage to more engineers
With Design Innovation, you can discover better designs, faster:
- Use built-in design exploration to consider 100s of design trade-offs
- Perform shape optimization without parametric CAD
- Employ flow topology optimization for additive manufacturing
3. Go faster
It’s great to have an accurate model in your digital twin and have the ability to run 100s of simulations to find trade-offs in design. But one important factor as well is to have the ability to run those simulations quickly enough to influence your design. A late simulation is not much better than no simulation!
With Streamlined Process, you can drastically cut your engineering time:
- Dramatically shorten the expensive model preparation time
- Save engineering time with automated & templated workflows
- Speed up solutions with integrated empirical, analytical & 1D models
With Early Insight, you can derive more value from your simulations:
- Leverage massive HPC scalability for both meshing and solving
- Scale-up and scale-out with flexible licensing and cloud solutions
- Speed up decision-making with advanced data analysis
4. Stay integrated
Engineering excellence is critical against the backdrop of increasing product complexity. It means that CFD can not be run in isolation – but needs to be connected to a full breadth of engineering tools from CAD to system simulation and test. Only if all these solutions work together can we accelerate the pace of innovation.
With CAD Embedded Solutions, you can minimize the number of design iterations:
- Enable CAD engineer to work in familiar environment
- Fit CFD into your workflow to create a “plug and play” approach
- Use native CAD model for analysis
