For further tips related to meshing for structural problems, take a look at the blog article “ How to Mesh Your CAD Model for Structural Analysis”. In other words, the geometry is divided into smaller parts, ensuring that the resulting PDEs are satisfied locally in each of the resulting small elements. Once the model is created, it needs to be discretized into elements. Pre-Processing: Meshing and Setting Up the Problem You can find some great tips in this YouTube video: “ Preparation of Geometry for FEM Simulation“.

Upon removal of engravings, it is essential to provide appropriate citations as required by GradCAD download licenses.

These engravings can significantly affect the mesh creation and need to be removed before using the models. One important word of caution when using CAD models from forums (such as GrabCAD) is to consider the small engravings made by authors. CAD models can also be found on several public forums. It is not always essential to start from the drawing board, however.

While Onshape currently allows up to 10 models to be stored in private, Autodesk Fusion 360 allows three years of free usage for students, designers, and hobbyists. Both of these tools are cloud-based and allow free usage. A convenient way to create CAD models is to use tools like Onshape and Autodesk Fusion 360. The geometry is generally simplified to create a computationally feasible and efficient model. One of the first steps is to create a reasonable geometry (or CAD model) that reflects reality as closely as possible. How to Learn FEA Creating the Geometry or CAD Model In this project, the impact of a human skull with and without a helmet was simulated with a nonlinear dynamic analysis. The purpose of a helmet is to protect the person who wears it from a head injury during impact. This is why it’s even more important to be absolutely certain of the accuracy of pre-processing. In addition, the job description of most engineers or designers does not include debugging the backend FEA program, they are only required to use the results.

Thus, if the inputs are not well understood, one will end up dealing with results that don’t make sense physically. Any computer program runs on the philosophy of garbage in, garbage out ( GIGO). With this in mind, it is essential to understand the pre- and post-processing aspects of the process in great detail. This corresponds to most of the industrial design departments where FEA is used. Appropriate inputs are applied and corresponding outputs are analyzed to make design decisions.

For someone using FEA from this perspective, an FEA software is a black box.

FEA Guide Engineer, Designer, and Hobbyist Perspective to Finite Element Analysisįor a professional engineer, designer, or hobbyist, the most important thing for learning FEA is to understand the right way to set up a problem.

Materials for getting started with SimScale can be found in the blog article “ 9 Learning Resources to Get You Started with Engineering Simulation“, and the YouTube video “ Getting Started with SimScale” is another great starting guide. To put your knowledge into practice as soon as you learn FEA, SimScale provides an easy to use, cloud-based platform that provides an interactive interface suitable for FEM simulations. Firstly, it is important to understand the perspective of the learner, whether the person is coming to FEM as a designer, hobbyist, engineer, mathematician or programmer. There are several generic resources and guides available on the Internet, but most of these are based on the one-size-fits-all theory. It is important to note that, in comparison with fluid mechanics problems, FEM software is more commonly used for solid mechanics problems. This article aims to be a list of valuable resources such as books, papers, validation examples, and more, all of which can help you learn or improve your knowledge about FEA. To understand and learn FEA in depth, this “What is FEA” SimWiki article is a great resource. The finite element analysis is the simulation of any given physical phenomenon using a numerical technique called finite element method (FEM). Engineers use this method to reduce the number of physical prototypes and experiments, and to optimize components in their design phase to develop better products, faster.
