    How to Design a Filtration Unit with SOLIDWORKS and solidThinking

    by Drew Buchanan on February 22, 2017

    Recently, as I was drinking a cup of tea, I appreciated having hot and clean water to drink. I thought about the process of obtaining that water. Specifically, about the filtration process. I wondered, what if I could simulate the filtration process within SOLIDWORKS? I quickly realized that I could do more than simulate the filtration process. I could simulate the casting of individual parts as well as the injection molding of specific parts of the apparatus.

    With that understanding, I set forth to utilize SOLIDWORKS Flow Simulation, SOLIDWORKS Plastics, and solidThinking’s Click2Cast to optimize the design. In this blog, I will lay out the steps to analyze a filtration unit with three different simulation and analysis solutions. I will also be hosting a webcast regarding everything we talked about in this blog.

      solidThinking: Empowering Engineers with the Right Design Validation Toolsets

      by David Roccaforte on February 13, 2017

      If you read a few of my SOLIDWORKS Simulation tutorials and finite element analysis blogs you will notice the recurring “tool” theme. As an engineer and gearhead, I love anything that will help me do my job better, whether it’s extracting a broken bolt from a cylinder solidThinking-Empowering-Engineers-with-the-Right-Design-Validation-Toolsets-1head or determining the optimal amount of material to meet performance specifications. Show me a tool that can help me do it better and I’m listening.

      One of my fondest memories as an engineering intern was the day my manager approached me with a tool catalog. This was before online ordering when PO’s were still done by hand.

      He said, “Pick out what you think we need for the mechanical lab, and order two of everything.”  As a student with an internship being able to fill up the gas tank felt like a luxury. Now I get to order any tool we might need? I was in heaven.

        SOLIDWORKS Simulation Tech Tip: Flow Solver Scalability

        by David Roccaforte on December 16, 2016

        Back in 2015, I tried an experiment comparing model size (number of cells) to memory needs and solve time. When I used SOLIDWORKS 2016, it was better at taking advantage of multiple cores as shown below. 

        flowsolverscalability

        The old solver started to lose advantages around 6 cores per job. You can see that the green curve is still upward sloping after 6 cores, that is the new solver.

          Save a Life – Optimize that Design with SOLIDWORKS Simulation

          by Drew Buchanan on November 30, 2016

          The beads of sweat drip off my forehead as I drill my climbing anchor into the rock. I maneuver the rope through the anchor’s 9mm slot for the rope to fit through. After the rope is tucked through the anchor, I place the strap through my carabiner and secure it, then begin my climb upwards. As I move upwards my left foot slips on a piece of shale, and my hands lose their grip. I fall backward hoping my carabiner and anchor system holds. Thankfully, the carabiner’s suggested 9 KN engineering rating holds fine, and I fall only five feet instead of the 100 feet to the mountain floor.

          I realize many of you may not spend your free time hanging out on the side of a mountain 100 feet in the air on a small rock ledge—trusting that engineers adequately designed a four inch curved piece of metal to hold your weight. Regardless, we all rely on products we use daily that have been designed and optimized by engineers for our safety.

            Save Time with SOLIDWORKS Simulation Feature: Blended Curvature-Based Mesh

            by Drew Buchanan on November 7, 2016

            Finite element modeling (FEM) continues to evolve and makes solving multiphysics problems easier and easier for users. No longer, are the days of dedicated engineers or programmers sitting in cubicles writing code to solve finite element problems. SOLIDWORKS Simulation has set the bar for making FEM easier for users while still being computationally powerful. In this blog, I will cover one of the newer capabilities in SOLIDWORKS Simulation that can save you a lot of time: the “Blended curvature-based mesh” feature.

              The Right Tool for the Job Part 3: Getting Your Fix with Fixtures

              by David Roccaforte on September 20, 2016

              In the first blog in this series, I introduced SOLIDWORKS Simulation Standard, our entry level but high value analysis package. In my second blog, I discussed the single body limitations in Sim Xpress and compared that with the extended capabilities in our more full featured tools. In this post, I will discuss the fixed constraint option in Sim Xpress and compare this to the capabilities of Simulation Standard.

                The Right Tool for the Job Part 2: The Single Body Limitation in Sim Xpress

                by David Roccaforte on September 8, 2016

                In my last blog, I introduced SOLIDWORKS Simulation Standard and how it is a lot of analysis power for the money. One point that I made is that there are many times when SOLIDWORKS users might be trying to do too much with the free Xpress tools or might not realize what they are missing in a more complete solution like Simulation Standard Professional or Premium. In this blog, I will discuss the single body limitation imposed by Sim Xpress.

                Sim Xpress allows only a single body and "fixed" constraints that stop motion on the chosen face in the X, Y, Z directions. The main reason for this limitation is that it prevents users from creating an unstable model by accident. Fix any face in X, Y, Z directions on a single body and you are going to have a stable model. In other words it's a slam dunk that the solver will able to solve for equilibrium and we can find a solution. This limitation guarantees a solution but limits the areas we can accurately extract stresses from and limits the types of situations we can accurately reproduce.

                    Simulation Standard: The Right Tool for the Job

                    by David Roccaforte on August 23, 2016

                    As the SOLIDWORKS Simulation Product Specialist at Fisher Unitech, I generally blog about tips and tricks using our analysis tools. Today’s blog covers one of the biggest engineering crimes that I witness these days: Trying to make your engineering problem fit the tools that you have, rather than using the right tool for the job.

                      Simulation Tech Tip: How can I simulate freezing water expansion?

                      by David Roccaforte on June 8, 2016

                      Now that spring is here ice is probably the last thing on your mind. Unless your designing a product where stress induced from freezing is a problem. One of my customers posed an interesting question.  How might we emulate freezing water in FEA ?

                       As you may know water expands when freezing and this can wreak havoc on any structure where water is contained or trapped.  Hence all the lovely pot holes in the spring punishing our fancy alloy wheels.

                        by David Roccaforte on April 13, 2016

                        I just received an email from my analysis colleagues at SOLIDWORKS  kicking off a series of Simulation training videos.  This is one of the great things about SOLIDWORKS there are so many places to learn and this is a great team to learn from.

                        Check out the video series.

                          30 Minutes to Smarter Design Decisions with SOLIDWORKS Simulation

                          by David Roccaforte on February 23, 2016
                          In the past 20 years, I have worked in manufacturing, product design and as a consultant/applications engineer for several simulation software companies. Working with many companies seeking to innovate and differentiate their products, I have seen personally that the decisions engineers make early in the design process often make the difference between success and failure of the products and the companies.

                            Flow Simulation Tech Tip: Hardware Benchmarks

                            by David Roccaforte on February 4, 2015

                            This past month I started a transition to new hardware which gave me a chance to compare four different machines side by side. Because I am commonly asked about what hardware is best for flow simulation, I though I would try a few benchmark experiments to see how different combinations of: Memory, CPU and Disk Speed affect solve times. I also wanted to get a feel for scaling by running with a different number of cores.
