    Two Great Tools Every SOLIDWORKS User Should Know (But Many Don’t)

    by Toby Schnaars on January 3, 2017

    As I’ve mentioned in previous blogs, I’ve been a user of SOLIDWORKS for 18 two-great-tools-every-solidworks-user-should-know-but-many-dont-1years and began teaching new and experienced users since 2001. Today we are going to examine two great tools in SOLIDWORKS that every user should know how to use, but many don’t:

    1. CTRL+Q = Force Regen
    2.  V.O.R. = Verification on Rebuild

    These two tools share the same theme: They both generate a rebuild, which is more thorough and elaborate, but takes a longer time to complete.

      Tips for New SOLIDWORKS Users Part 2: Keep Your Sketches Simple

      by Toby Schnaars on October 12, 2016

      Welcome back to our series of tips for new SOLIDWORKS users. As I mentioned in my last blog, I started teaching SOLIDWORKS CAD software to both new and experienced students in 2001.  This blog series covers three great tips I’ve learned over the years to help new SOLIDWORKS users get started off on the right foot:

      1. Always start your sketches the same way – and know when you are in sketch mode
      2. Keep your sketches simple
      3. Fully define, every time

      My last blog covered the first tip. Today, we will move into the second: Keep your sketches simple.

        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.

            SOLIDWORKS FLOW SIMULATION: Animating Transient Flow Runs and Solver Iterations

            by David Roccaforte on September 24, 2013

            In this simulation tech tip, I am going to cover using animations to display the auto mesh refinement splitting cells, since it is useful for watching steady state flow solutions develop, as well as viewing multiple time steps in a transient solution.

            1. Make sure we are saving the steps during the Flow solution. Open the "Calculation Control" dialog. This is accessible from the flow feature manager, command manager, and the solver menu window:

             

            1a. Choose the saving tab and enter how often you want to save results.
            1b. The individual iteration results will be saved in your Flow folder for each iteration as  "r_XXXX.fld"
            These are individual result sets which will be referenced to create your animation. Be careful: this is a good way to fill up your hard drive for larger models with small times steps.CONTINUE READING:

            2. Solve the flow model.

            3. Load the results (last iteration is default) and create a plot that you want to animate, such as a cut plot or surface plot.

            4. To begin creating the animation, either right click "Animation" in the feature manager and choose Insert or right-click the desired result set to animate such as a cut plot and choose Animation.

            5. Once the animation pane appears, you will want to drag the study "control point" all the way until the start of the animation (to the left).

            6. To bring the individual time frames/iteration in, you will then click the "Movie" icon.
            6a. Enter the desired duration of the animation, and click "Next."
            6b. Choose rotation or not; you can still rotate the model using control points and views later if you choose "no" here. The rotation will add key frames for a simple rotation about the global axis. Click "Next."
            6c. Select "Scenario" to animate multiple timesteps. Click "Next."
            6d. Choose "Uniform" or "Proportional" and select the start and finish from the sliders if you don't want to include all the timesteps/iterations results.

             

            6e. Now you will see a "control point" for each iteration brought into the animation.
            7.  To determine when the features are displayed in the timeline, you can insert and drag the "control points" for that feature.
            7a.  To choreograph different plots, you can adjust "control points" for the individual features to begin and end at different times or overlap etc... (see the video we phase out the mesh cutplot then phase in the flow stream cutplot.)
            7b. To change the view during the animation, you can place "control points" in the animation pane to move from one view to another. First, you must right click the project name and unselect "Lock Orientation." Each control point is a specific view orientation, and when they are connected, the model moves from one view to the next dynamically. To adjust the orientation at a "control point," drag the slider bar to the point and adjust the model view. (See the video below).
            8. Now you can hit the play button and the view orientation will change based on your view "control points." In addition, your feature plots with "control points" will update based on the solver iterations. You can also save the animation as an .avi file by clicking the record button. This can be useful since the frames can take some time to load.
            Watch the video below a couple times and you will see that it's a pretty quick process.
