Computational Fluid Dynamics in the SOLIDWORKS Ecosystem

SolidWorks is one of the almost popular CAD packages in manufacture use today. As it has gained in popularity SolidWorks has adult into not only a complete CAD package, only an impressive simulation suite as well. Ane of these simulation programs is SolidWorks Menses Simulation. SolidWorks Flow Simulation preforms what is known as Computational Fluid Dynamics (CFD) computations. Simplified, this means that it calculates fluid behavior nether specific conditions. Today, we'll look at some of the basics of SolidWorks Flow Simulation including how to admission catamenia simulation, the basics of the menses simulation magician, and running a unproblematic simulation.

An Intro to Flow Simulation

As we mentioned above, SolidWorks flow simulation is a CFD solution that integrates perfectly into the SolidWorks user interface. For those who wish to utilize this software, access is bachelor as a split up bundle from the basic SolidWorks license and must be purchased separately. This frequently comes with quite a hefty price tag, so knowing alee of time that you tin do good from the use of this software is paramount in deciding if you should buy it. To that betoken, while flow simulation is fairly user friendly, any CFD solution tin can merely be fully utilized past someone with a stiff noesis of fluid dynamic principles. While most anyone can prepare up a simulation with the right guidance, ensuring that results volition be valid, and being able to translate those results, requires a certain corporeality of knowledge in the field of study. Additionally, understanding the capabilities of the software and ensuring that it is a good pick for obtaining results that you need is also important when determining if information technology is worth the cost. If yous still think that SolidWorks Flow Simulation may be right for you, lets go ahead and accept a look at the basics of how it works and what it's capable of,

Period Simulation Basics

When considering the basics and capabilities of flow simulation, a great place to start is ever the literature that is provided past SolidWorks (we provide some links at the end of the article). We won't have the fourth dimension to rehash all of that hither, instead, let's take a look at the capabilities by apace working through the Menses Simulation Sorcerer. To access flow simulation, first get to "Add-Ins" and make certain that the menstruum simulation check box for "Agile Add together-Ins is selected.

Once the add-in is active, yous can activate a new project by going to Tools > Flow Simulation > Project. From there yous can see that you have the "New" option too as the "Wizard" selection.

For the purposes of this article, we will select the "Wizard" option. Starting a "New" project from scratch is geared towards advanced projects, and users who are already well versed in the use of SolidWorks flow simulation. When you select the project wizard you see the following carte.

The wizard starts with the "Project Name" dialog. Here nosotros can name the project, add together any relevant comments and select the configuration that we intend to use. If we click the arrows on the correct side of the window, we tin can besides run across all of the steps that the wizard volition walk us through. This as well allows us to leap dorsum and forth between steps if necessary.

We volition name our new project "U-Bend Project." clicking next brings us to the "Units system" dialog. From hither we tin select a predefined unit system, ascertain our own unit system, and view all of the divers units and levels of precision for whatever of the parameters that may be involved in the project.

This list is quite long, and includes units that many people unfamiliar with fluid mechanics will not have encountered before. You can kickoff to see why a background in fluid sciences is necessary to become the nigh from this powerful software. For this example we will apply SI units. Our next set of options comes in the grade of the "Analysis type" dialog window.

Here nosotros have some options that once again require a fluids groundwork to fully understand. Since the purpose of this commodity is primarily introductory, we volition not describe all of the options available hither, merely provide a brief overview of the options you see above. The analysis type gives an option betwixt Internal and External flows. As would exist expected, Internal flow describes flow in a closed book, and external flow describes flow over objects in an open up space. The options for "Consider closed cavities" provide options to exclude certain areas to reduce adding fourth dimension. "Physical features" options allow you to alter the project to include the listed options. Some of these options take other parameters when you select them, some tin simply be active if others are not, and others crave other options to exist active to exist selected. The wizard volition tell you of these limitations every bit you make selections, but an agreement of what these options do is necessary for implementing them correctly. For this project, we will select internal menstruum, and nosotros won't use any of "Physical Features" options, just know that they are options for studies within the flow simulation piece of work space. The adjacent dialog window is labeled "Fluids." This window allows us to select what fluids volition be present in the study, as well every bit what the flow atmospheric condition will be.

We can see from the dialog box above, that nosotros take a number of options for the fluid that include liquids and gasses. If nosotros cull to, we may as well define a custom fluid by selecting the "New" button in the superlative right corner of this dialog window. Nosotros tin besides select our flow characteristic to be laminar, turbulent, or a combination of both. One time you have added a fluid other options may get available equally shown below.

You may add multiple fluids to the projection if you desire, and your list of selected fluids will let you to select which one to treat as default. For this example we will select "Water ( Liquids )" with the "Menstruum Type" gear up to "Laminar and Turbulent" and "High Mach number flow" selected. Moving on to our next set up of options, we meet wall conditions.

Equally you can see at that place are merely ii default options here. The first is the "Default wall thermal condition." We won't spend then much time on this option as it requires some knowledge of thermodynamics to sympathize properly, and, if you have this knowledge, the options are adequately cocky explanatory. That said nosotros will try to give a brief caption that can be easily understood since you must option an option. The outset option is "Adiabatic wall" which can be thought of as perfectly insulating. The next two options are "Heat flux" and "Heat transfer rate", and they are both unlike means to describe how hands the wall transfers estrus. Finally, we take "Wall temperature" which maintains the wall at a constant temperature throughout the simulation. The only other pick here is "Roughness" which changes how the solver will perceive the surface cease of the wall. We will leave these options at their default setting. The last category is labeled "Initial Atmospheric condition." The options found here will dictate the starting weather of the fluid in your simulation.

Starting at the top, "Parameter Definition" should usually be left as "User Defined," simply every bit you lot proceeds experience, you lot may too import initial weather condition from the results files of some other simulation. The "Thermodynamic Parameters" allow united states of america to choose betwixt setting pressure and temperature, pressure and density, or temperature and density. For our "Velocity Parameters, we can choose either the velocity or the mach number. Regardless of our selection, this will be gear up as a vector in "X," "Y," and "Z". Finally we may set the turbulence in either intensity and length or by energy and dissipation. These fields are set to standard temperature and pressure weather condition by default and that is what we will use for our example.

Once nosotros take finished using the wizard this is what our example looks similar. The period sorcerer automatically creates a box that defines our computational domain. Note that with an internal flow project, there must be an enclosed volume. The inlets and outlets should be covered with seperate bodies called lids. For clarity nosotros tend to use color to define lids, using transparent red for inlets and transparent greenish for outlets. If you practise non have lids, you volition receive a warning upon finishing the wizard and will exist prompted to use a tool that helps make lids automatically. The concluding things this intro will cover are boundary weather and goals. To define a boundary condition, we hide the main body so that we may select the inner faces of our lids every bit shown below.

There are more options than are beneficial to explain here just know that this can set the conditions across our lids. In this case, we set our inlet to button our default fluid in at a constant inlet volume flow of .8 m^3/s. Similarly the outlet will be ready but to a constant, but rather than a velocity, nosotros declare the opening to exist at atmospheric pressure.

Finally we must declare a goal. This is merely a parameter which nosotros are interested in monitoring. For this project we will select the minimum and maximum for "Velocity" and "Velocity X."

Now we are set up to run the study. By right clicking on the title of our project, we are presented with the run selection. When nosotros select to run the study, the solver window will popular up automatically equally shown below.

As you can run across, this window will warn united states as it solves if in that location is anything wrong with the projection. In this case we have a warning stating that there is negative pressure. To locate this problem section we can declare a cutting plot.

Once we have our settings where we desire them, a department view will assistance the states see the results.

It is airplane to see with this view where the negative force per unit area is occuring. As you can see, tools like this could testify invaluable for evaluating a new design. In this case, the inlet flow volume is far college than would normally be seen for this type and size of U-curve, which is probable why we take the issue. If we reset the inlet menses to something more than reasonable, such equally .01 m^3/due south, the event disappears, and we can proceed studying our desired parameters.

Conclusions

Solidworks catamenia simulation is a powerful tool. While it does require specialized noesis in fluid mechanics and thermodynamics, hopefully you can see that this software has powerful abilities to clarify a pattern. When utilized properly, SolidWorks menses simulation can place and help eradicate problems even before the first concrete prototype is made.
