Be sure to check that your operating environments are set up correctly before running simulation analysis.ĭata interpolation is crucial to FEA simulation in SOLIDWORKS since stress and strains are averaged from node to node. You’ve probably heard the phrase, “garbage in, garbage out.” In the context of FEA, setting improper loading or boundary conditions skew your results. Learn more about meshing in this SOLIDWORKS tutorial. Luckily, SOLIDWORKS makes it easy to understand the different mesh types. Knowing these mesh types, when to use them, and how they interact is another crucial part of greater success in SOLIDWORKS Simulation. In SOLIDWORKS, there are three types of mesh: solid, shell, and beam. While refining the mesh increases the accuracy of the model, it’s important to note that the mesh density compounds computational time. Therefore, a finer mesh (element size) will result in a more accurate representation of the actual designed model. Simulation is conducted on a part, body, or assembly and analyzes the summations of these discrete elements - not the actual model. SOLIDWORKS models are broken up into discrete elements, forming a mesh. Knowing this limitation of FEA and how to identify it is a necessity: this will help you identify calculation errors in the future. When this happens, the stress will grow infinitesimally at the inside corner. But removing this fillet has led to a stress singularity. A fillet has been removed from the inside corner to simplify the model and decrease computational time. However, oversimplifying a model can lead to stress concentrations. It’s often recommended to try simplifying your models prior to running any SOLIDWORKS simulations. These assumptions may sound like negative limitations of using FEA however, knowing these assumptions will help you be much more conscious and successful when conducting analysis despite the drawbacks.
FEA Assumptions to Know When Working with SOLIDWORKS Simulation In this article, discover important things to know about FEA that will help you run more successful simulation analysis and make informed design decisions based on your results. But running analysis in a software tool requires some key knowledge and technical skills. More and more engineering teams are using complex FEA software, like SOLIDWORKS Simulation, to test their designs. FEA is an essential step in the product development design cycle that can help you lower development costs and design a more robust and reliable finished product.
Most engineering design professionals are familiar with finite element analysis (FEA): a numerical method for predicting how an object will react to real-world forces, vibration, and other physical effects.
