SOLIDWORKS Flow Simulation: Lid creation for non-planar faces

What are lids and why do we need them? SOLIDWORKS Flow Simulation supports two main study types, internal (flows bounded by outer solid surfaces, e.g. tanks, office space, etc.) and external (not bounded by outer solid surfaces, e.g. flow over a wing). Internal flow studies often contain geometry that have inlets and outlets. Flow Simulation requires that these inlets and outlets be bounded by a face. These bounded faces will then contain the info necessary to describe the flow for […]

SOLIDWORKS Simulation Case Study: Stress concentrations occurring in places they shouldn’t or too high?

Finite Element Analysis (FEA) results are dependent on model, material, and boundary conditions. However, the boundary conditions have the greatest effect on the results. The boundary conditions in SOLIDWORKS Simulation must reflect the conditions in the physical experiment. A good example is the scissor lift shown below (Figure 1). As we all know, scissor lifts are designed with legs that are collapse and expand. These “legs” are pinned together. If a load is placed on the lift, then the whole structure […]

SIMULATION: Resolve Contact Set for Bodies That Overlap

Have you ever seen bodies pass through each other in SOLIDWORKS Simulation? You cannot always easily observe overlapping behavior. This depends on if deformed result display is used and, if so, which deformation scale is selected. In the example below I created a multi-body part, fixed the 2 rectangular parts in place, and added a horizontal load at the end of the L-shaped part. I bonded the smaller rectangle body which acts as the support for the L-shaped body. To […]

SOLIDWORKS Simulation: Which Solver should I use?

SOLIDWORKS Simulation provides users with several options when selecting a solver, they include: Direct Sparse, Intel Direct Sparse, Large Problem Direct Sparse, Intel Network Sparse, and FFEPlus. With all these options how does a user know which one is correct for their simulation study? Fortunately, SOLIDWORKS has a procedure to automatically select solvers. Automatic Solver Selection SOLIDWORKS uses the FFEPlus iterative solver by default unless certain conditions are present. Under these “certain conditions” the Direct Sparse solver will be chosen […]

Stratasys Connex 3D Printers

Stratasys Connex 3D Printers Who is Stratasys? Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota. Crump thought of creating shapes layer by layer and of a way to automate the process. In April 1992, Stratasys sold its first product, the 3D Modeler. Crump patented fused deposition modeling (FDM) technology and in 2003, FDM was the best-selling rapid prototyping technology. On April 16, 2012, Stratasys announced that it agreed to merge with privately held Objet Ltd., a leading manufacturer of 3D […]

SOLIDWORKS Static Simulation Highlights

Who uses Static Simulation? SOLIDWORKS linear static stress analysis enables designers and engineers the power to validate their design quickly and efficiently. Validation is done within the SOLIDWORKS application utilizing a familiar user interface and eliminating the need to export data to another software package. Linear stress analysis no longer must be delegated as a post design process. The validation and design become a simultaneous process instead of sequential. What is Static Simulation? SOLIDWORKS Simulation uses finite element analysis (FEA) methods to determine the […]

SOLIDWORKS 2018 What’s New – Flow Simulation Noise Prediction – #SW2018

SOLIDWORKS 2018 What’s New – Flow Simulation Noise Prediction – #SW2018 For many engineer’s noise intensity due to flow turbulence is a critical design criterion. Designers must consider noise output from industries as diverse as kitchen appliances, automotive, and defense. Unfortunately, not until recently, users could only interpolate a general sense of noise output by viewing turbulence plots. Now, in SOLIDWORKS 2018, Flow simulation has new capabilities to show acoustic plots. The image below utilizes decibel (dB) units to display acoustic […]

SOLIDWORKS 2018 What’s New – Flow Simulation Plot Callouts – #SW2018

SOLIDWORKS 2018 What’s New – Flow Simulation Plot Callouts – #SW2018 SOLIDWORKS users have long been able to add callouts for maximum and minimum stress in SOLIDWORKS Simulation (FEA). Callouts point the user to the area with the max/min plot values without having to search for these extremes. In the past users lacked min/max callouts in SOLIDWORKS Flow simulation (CFD). Users had to resort to probing the plot in various locations and viewing a min/max table. The table shows the […]

SOLIDWORKS 2018 What’s New – Plastics – Density Results at End of Pack Analysis – #SW2018

SOLIDWORKS 2018 What’s New – Plastics – Density Results at End of Pack Analysis – #SW2018 Plastic injection molding is the most cost effect method to mass produce parts. But it represents a significant initial investment. For this reason, many mold designers use SOLIDWORKS Plastics to avoid costly rework. The mold process uses a multi-staged process: fill, pack, cool, and eject. This blog will focus on the new results plot available in the pack stage; density results at end of […]

SOLIDWORKS 2018 What’s New – Plastics: Clamp Force in Machine Opening Direction – #SW2018

Plastic injection molding is the go to manufacturing method when plastic parts must be mass produced. However, these molds are precision machined and highly expensive both to create and rework. For this reason, many manufacturers utilize SOLIDWORKS Plastics simulation to reduce mistakes and rework. SOLIDWORKS Plastics provides the results for many different parameters, one of which (clamp force), will be discussed in this blog. What is a clamp force? Plastic injection molding is the process of injecting molten plastic, under pressure, into a […]
