When the products you design involve liquid or gas flow, how can you test their performance for real-world conditions? This is where computational fluid dynamics (CFD) with SOLIDWORKS Flow Simulation software comes in.enables you to run “what if” scenarios and efficiently analyze the effects of fluid flow, heat transfer and related forces on or through components. This allows you to compare design variations quickly to make better decisions so you can create products with superior performance. Read on to learn more about CFD with SOLIDWORKS Flow Simulation.What is Computational Fluid Dynamics?Engineers use a number of analysis methods to understand the impact of the world around us on their designs. A key analysis method is CFD, which is used to analyze and solve problems that involve the impact of fluid flow, including liquids or gases.CFD is applied to a wide range of engineering problems in many industries, including high-tech electronics cooling, aerospace and aerodynamics analysis, industrial systems design, engine and combustion analysis, and many others. What is SOLIDWORKS Flow simulation?SOLIDWORKS Flow is a general-purpose fluid flow and heat transfer simulation tool integrated with SOLIDWORKS 3D CAD. You can use this CFD solution to simulate both low-speed and supersonic flows.SOLIDWORKS Flow simulation enables true concurrent engineering and brings the critical impact of fluid flow analysis and heat transfer into your workflow to ensure your designs will perform optimally.
SolidWorks Flow Simulation: Parametric StudiesAnyone who has used SolidWorks Simulation for some time probably knows about the Design Study functionality, and maybe even the Optimization functionality found in Simulation Professional. Users of Flow Simulation have been asking for similar functionality, but all we had to work with was a single-parameter optimization study.
I can finally say that now with SolidWorks Flow Simulation 2013, we can run multiple what-if scenarios while changing multiple variables!.Anyone who has used for some time probably knows about the Design Study functionality, and maybe even the Optimization functionality found in. Users of have been asking for similar functionality, but all we had to work with was a single-parameter optimization study. I can finally say that now with SolidWorks Flow Simulation 2013, we can run multiple what-if scenarios while changing multiple variables!I was helping a colleague of mine with a Flow Simulation project when I was first exposed to the new parametric study in 2013. I was helping to create a custom Porous Media within the Engineering Database, but I needed some input data like a graph of Pressure Drop vs. Flow Rate:How was I going to accomplish this? SolidWorks 2013 Flow Simulation Parametric Study to the rescue!This was the customer’s example:To make dimensions easier, I modeled this in SolidWorks:Before I ran this study, I wanted to take a look at this mesh to make sure it was adequate.
In particular, I wanted to make sure that the mesh captured the details of the grating that I modeled. I started with the initial mesh slider at “3”. At first glance, it looked as though the perforations were captured:One thing to be careful about though; the option to “Use CAD Geometry” is turned on by default in the cut plot properties and can be deceiving. This is what my mesh really looked like:Definitely not what I was expecting! The recommendation is to have “Use CAD Geometry” option turned off.I needed to refine my mesh, either using the automatic settings (the slider bar) or manual mesh refinement. I opted to use the manual mesh refinement and increase the “small solid feature refinement” level to 3.Much better!
I knew I needed to run several studies, each time increasing the volume flow rate and monitoring the pressure drop across the perforated plate. Until 2013, the only way to do this was to manually change the inlet boundary condition and rerun. With the release of SolidWorks Flow Simulation 2013, I could now use the updated Parametric Study tool!
I used the “What-If” setting; there is also a “Goal Optimization” which works similar to past versions.I chose which variable I wanted to change (this can be either a flow parameter or a dimension) and what values to use, which goal(s) I wanted to monitor, and then ran it.You can export your results to Excel; I had this as my final output:My colleague used the raw data for his Porous Media definition and he was good to go. As you can see, the new Parametric Study in SolidWorks Flow Simulation 2013 opens up new possibilities, many of which were available to people using Design Studies in SolidWorks Simulation. Whether you are trying to optimize pipe length or being lazy and batch running multiple what-if scenarios, the new 2013 Parametric Study is the way to go! Wendy, to give you a couple a couple steps:1. Create a SolidWorks Flow study like you normally would.2.

Go to Flow Simulation DropDown Solve New Parametric Study3. On the Input Variables Tab, you can either select “Add Simulation Parameter” or “Add Dimension Parameter”4. You can pick to vary as “Range with Number”, “Range with Step”, or “Step Around”. Double click on the Variation Type item to adjust the numbers.If you need additional help, the best resource would be your SolidWorks reseller.
