A 3D to 1D System Level Thermo-Fluid CFD Workflow
Real Multidimensional CFD Is Here
Systems engineers who are working in industries such as automotive, aerospace, oil, gas, power, and energy use both 1D and 3D computational fluid dynamics (CFD) software to design their products. For example, they use 1D CFD or “thermo-fluid simulation” to discover the thermal and hydrodynamic behavior of complex piping systems. And they use 3D CFD to run numerical analysis, equations and algorithms and simulate the interaction of gases and liquids. Mentor Graphics provides both 1D CFD and 3D CFD capabilities with its FloMASTER and FloEFD products.
The new white paper, “Simulation Based Characterization – A 3D to 1D System Level Thermo-Fluid CFD Workflow” by Dr. Robin Bornoff, describes how to use both of these tools in a simulation-based characterization workflow, where FloEFD to be used to characterize complex geometries for subsequent use within a FloMASTER simulation. He provides us with a description of the methodology used for an automotive engine cooling application that illustrates how 3D to 1D can be combined.
Although 1D CFD software is fast to implement, significant amounts of data are required when it gets down to describing individual components accurately. To address this issues, FloMASTER comes with complete descriptions of components, including pipes, valves, bends, pumps, reservoirs, etc., which are based on extensive experimental measurements that characterize behaviors with high accuracy.
A tightly-coupled, 1D-3D CFD methodology provides increased accuracy for components while minimizing the computational resources and execution times at the system level. The result is virtual prototyping throughout the design process. Now systems engineers can examine more variables across a wider range of design scenarios and achieve optimal system and component design. They also can quickly create a digital twin of an existing design or prototype.
FloEFD is built into major MCAD systems such as Creo, CATIA V5, Siemens NX, Solid Edge and SolidWorks to help promote the democratization of 3D CFD analysis for design engineers. This enables frontloading- a practice where CFD is conducted earlier during the design process.
