Making Sense of SOLIDWORKS Simulation Meshing – Part 1 As an Application Engineer specializing in SOLIDWORKS Simulation, I often get asked, “How do I know if I have a good mesh?” The simple answer is, it’s not so simple. This is the first blog in a 3 part series that I will be posting about meshing. In this blog we will discuss meshing considerations for study types and purposes as well as mesh convergence considerations. The next two blogs in […]
Nonlinear Material Models in SOLIDWORKS Simulation If you are using SOLIDWORKS Simulation Premium, you have access to the Nonlinear study type. One of the advantages of this study type over the Linear Static study is the ability to apply loads and boundary conditions that vary over time. Another is the access to multiple material models that represent nonlinear material behaviors: Nonlinear Elastic Hyper-elastic Elasto-plastic Super Elastic Nitinol Linear Visco-elastic Creep Let me give you a brief description […]
SW Plastics Runner Design – Control Valves Increased realism in SOLIDWORKS Plastics comes with the introduction of control valves in the 2017 release. A technique used in the injection molding industry known as Sequential Valve Gating (SVG) incorporates the use of control valves when multiple gates are used in the injection process. The advantages of SVG are numerous, especially for larger and more complex parts, including greater control of weld line locations, minimization of the adverse effects of over-packing, and […]
Was it really last year that Vik wrote about Two Neat Additions to Simulation in 2013? How time flies! For all its power, the addition of Submodeling studies for Simulation 2013 has seemingly gone unnoticed by our Simulation user base. In most cases, we are usually interested in the performance of a small portion of the model, maybe a part or two of the whole design. In order to get to that area of interest, we need to analyze a […]
SW Motion is a great tool to understand kinematics of a mechanism. The 2012 version of Motion has a great new feature. If you use actuators and sensors to control the movement of a mechanism, you can optimize the entire design virtually. Typically, to get the system correctly configured would take many trial and errors on an actual machine or many hours of hand calculations. A user can simply input sensors as a variable and the optimization tool to […]
Fishing is all about enjoying nature. The calm serene water, calling you to sit back, relax, sun bathe while you catch dinner. Every summer weekend, Rod takes a break from rigors of work and impress on his family his fishing skills. This seat has experienced many joyous moments, passed on wisdom, and helped create some amazing memories. The seat is mounted to the floor using a pedestal and base. On a recent trip, Rod was enjoying his beer and suddenly […]
A Pressure Vessel study combines results of multiple loads and understand behavior of any cross section as per ASME standards. A typical load includes internal pressure, temperature rise and earthquake loads. So to start with a user will create different static studies to understand design behavior under each load type (pressure, temperature, etc). Using SOLIDWORKS Simulation users can easily study the effect of multiple loads on designs. Once a Pressure Vessel Design is run, users can use […]
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 […]
ISO 14000 addresses various aspects of environmental management. The standards, ISO 14001:2004 and ISO 14004:2004 deal with environmental management systems (EMS). ISO 14004:2004 provides guidelines on the elements of an environmental management system and its implementation, and discusses principal issues involved. ISO 14001:2004 specifies the requirements for such an environmental management system. Fulfilling these requirements demands objective evidence which can be audited to demonstrate that the environmental management system is operating effectively in conformity to the standard. An EMS meeting […]
It is observed that repeated loading and unloading weakens objects over time even when the induced stresses are considerably less than the allowable stress limits. This phenomenon is known as fatigue. Each cycle of stress fluctuation weakens the object to some extent. After a number of cycles, the object becomes so weak that it fails. Fatigue is the prime cause of the failure of many objects, especially those made of metals. Examples of failure due to fatigue include, rotating machinery, […]
