The Value of Simulation Web Series: Part Three

We just concluded Part 3 of the SOLIDWORKS Simulation and SIMULIAworks webinar series. If you missed the previous webinars, you can watch them on-demand by using the links below. The Value and Productivity themes here show the depth and breadth of the SOLIDWORKS Simulation solutions.

Theme #1 – The Value of Simulation / Which Design is the best?

Part 3: “Using CFD to drive Product Performance”

Using Computational Fluid Dynamics (CFD) for fluid flow and heat transfer simulation improves product performance and helps you make better, more informed design decisions.

The webinar provides a quick introduction and a high-level overview of SOLIDWORKS Flow Simulation capabilities.

Specific examples show how you can leverage the integrated SOLIDWORKS and SOLIDWORKS Flow Simulation environment to determine which design is the best based on a certain expected performance level.

Example #1: Piping System – Comparing different design scenarios in a piping system. The best design here is the short pipe with the Vortab insertion sleeves as shown in the result summary.

Example #2: Electronics Enclosure – In this example, we first select which packaging works better for thermal distribution: solid cover or vented cover design. Then, we address how many fans are needed and what the best location of these fans should be for optimal cooling. Results below show the temperature distribution in some of the different design cases in order to choose the best package option as well as the number of fans needed along with their optimal locations.

Example #3: Heat Exchanger – In this example, the Optimization tool in SOLIDWORKS Flow Simulation is used to automatically drive the angular flap angles to their optimal values in order to achieve an equal flow rate of the fluid in each one of the channels. Optimization uses a Design of Experiments (DOE) technique by running different experiments and using a user-defined objective or goal to choose the optimal solution.

Next in the webinar, some technical tips were discussed on Meshing: 2D Analysis, Porous Media and Exporting results to FEA.

Finally, some industry examples highlighted the breadth and depth of how customers are using Flow simulation to solve their engineering fluid dynamics problems across many industries.

Theme #2 – Improving Productivity using SOLIDWORKS Simulation

Part 3: Addressing Vibration Issues – Statics vs. Dynamics

Shaking, shock and something resonating with you are expressions that we use in everyday conversations and signify stronger emotions or responses on our part to different excitation. Similarly, in Structural and Mechanical Engineering, we may have to go beyond a basic linear static FEA and study the dynamics behavior of a design. In this webinar, we first cover the significance and some fundamental concepts in vibration analysis.

Terminologies, such as frequency, damping, harmonics and Power Spectral Density, were explained. Natural frequency and linear dynamics are reviewed, more specifically the study types of Time History, Harmonic Response, Random Vibration and Response Spectrum.

Three examples were then presented using SOLIDWORKS Simulation, a natural frequency analysis contrasting physical and virtual prototyping of a thin plate, a time history analysis of a billboard with a base excitation and a random vibration analysis of a printed circuit board.

Two tech tips were shared to improve accuracy in linear dynamics based on the mass participation factor and for a better user experience by saving selected solution steps to reduce the size of the output file. A few examples were given from different industries, highlighting the applicability of a dynamic simulation.

Nonlinear Dynamics was also briefly reviewed, summarizing the new capabilities offered under the SIMULIAworks product portfolio on the 3DEXPERIENCE platform. These include Structural Performance Engineer and Structural Mechanics Engineer that use the SIMULIA Abaqus technology for Implicit and Explicit Dynamics.
