MESHING AROUND FEA
Pre-Processing and Meshing for
Finite Element Solvers
What makes a good simulation analysis in engineering design is directly dependent on the quality of inputs that you provide to any of the tools at your disposal. And understanding how each of the variables pieces change the results, when to use each conditions and shapes becomes essential.
Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain. The mesh influences the accuracy, convergence and speed of the simulation. Furthermore, since meshing typically consumes a significant portion of the time it takes to get simulation results, the better and more automated the meshing tools, the faster and more accurate the solution.
Our goal in this hands-on course is to guide you to become a more confident professional when it comes to using Finite Element Analysis (FEA) no matter what different design challenges.
Having a solid and enforced knowledge of the latest simulation tools, we will show you the importance of proper meshing, each of the features you need to take in consideration to create a robust input file, how to select the correct mesh size, what to do to modify the mesh generation, take in consideration the different types of meshing and proper refinements around the geometries needed, and improving the mesh in your design.
