SOLIDWORKS SIMULATION TECH TIP: Transferring Flow Loads to Shell Elements

EmailFacebookLinkedInTwitterShare

In SOLIDWORKS, we have the ability to take advantage of an integrated interface where we can use multiple simulation tools. If you are using Flow Simulation and Simulation (FEA), you can export Flow Simulation loads to FEA studies. In the following example, I ran flow over a truck body and exported the pressure loads to SOLIDWORKS Simulation. The goal of this particular problem is to identify the displacement of a truck cap as a function of the aerodynamic pressures. In […]

The SOLIDWORKS Flow Simulation team has added powerful new functionality to their arsenal,  Rotating Mesh Regions.  Rotating mesh regions or “sliding mesh regions” allow the user to rotate geometry in the model and drive the fluid of the system.  If you are designing any device that utilizes, impellers, propellers, or other rotational apparatus Flow Simulation can provide results such as flow rate, pressure drop, velocity, and many more, all based on the rotation of the geometry.  A transient or time […]

2015 Flow Simulation Compare Tool Improvements

EmailFacebookLinkedInTwitterShare

Every new release of Flow Simulation adds more functionality, faster solution times, and customer requested enhancements.  One of the 2015 enhancements is the Study Compare Tool overhaul.  In 2014 a user could compare any active plot and goals between projects in the same model.  This is very useful functionality when comparing between different design options under the same flow conditions.  Only being able to compare active plots lead to some drawbacks and some fumbling for what you actually wanted to […]

Circuit Works and Flow Simulation Working Together

EmailFacebookLinkedInTwitterShare

When you think about it, it makes sense that different parts of our SOLIDWORKS Software work together to make a total package.  Keeping in this tradition now in 2014 Circuit Works and Flow Simulation work together to make your life easier. 2014 Flow simulation now imports the Circuit Works component properties and applies them automatically as boundary conditions in your Flow Simulation setup.  Previously these properties would be input manually.  Now we can import ECAD file PCB or Component Thermal Properties […]

As time progresses and fuel prices increase, you might have noticed some changes to the tractor trailers you see on the highway. Fairings on tractors have been common for quite a while; however, side skirts and extended “tails” on the trailers are relatively new additions. To satisfy my curiosity on the effectiveness of these devices, I’ve performed a virtual experiment using Flow Simulation. Watch the quick video below to see the results of the test. For more training and tutorials […]

Power on : SOLIDWORKS Flow for Electronic Components

EmailFacebookLinkedInTwitterShare

To optimize the thermal performance of electronic components and ensure their operation, designers and engineers need to simulate both the environment and heat loads in and around components, PCBs, and complete products. SOLIDWORKS Flow Simulation, augmented with the Electronic Cooling Module, enables you to easily perform complete thermal analysis and test design changes during the design phase. Lets consider a halogen floodlight with an aluminum housing, which contains a quartz glass front window, a silicone gasket, an aluminum internal reflector, […]

One of the things that we emphasize in our Simulation Training classes is simplifying the model. It’s an easy concept to understand – the simpler the model, the faster you’ll get results! For designs that use SolidWorks’ weldment functionality, Simulation will automatically make one of the most significant idealizations of a model. 3-D geometry is idealized into a 1-D finite element for the mesh, a Beam element. Here is a simple example where two standard c-channel structural members come together […]

Valve Design using SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

A designer needs to understand how a concept design performs and then quickly, study design variations to come up with most efficient design. This factor alone makes Flow Simulation the perfect tool for engineers.   We will use a Ball Valve as an example. The user closes the internal volume of pipe using extrusions called lids. SOLIDWORKS Flow Simulation works with the SOLIDWORKS geometry, hence there is no need to define a fluid volume. Based on the enclosed region between […]

The Capabilities and Limitations of Flow Simulation

EmailFacebookLinkedInTwitterShare

One of the grey areas of Simulation swirl around the SolidWorks Flow Simulation product-line, where the capabilities and limitations are critical to ensure successful implementation. Earlier this week, we had a potential customer inquire into the functional capabilities of Flow Simulation. Flow Simulation is an excellent mid-range fluid flow product if you are trying to simulate anything from liquids to gas flow. It can be utilized in a wide range of applications from electronics to valves to HVAC to medical and […]
