For example, if your geometry shares nodes between common faces (or edges), it’s important to decide if it will be a conformal or nonconformal mesh. Using Ansys SpaceClaim, the name plate on the geometry was easily defeatured to avoid doing a potential unnecessary analysis on the plate.Īnother important aspect of prepping your CAD model for simulation is describing the relationship between two or more parts in your geometry. You may not need to learn the physical effects of this name plate, so the plate can be defeatured to avoid creating a mesh, which saves meshing and solve time.

But for a simulation, you may not need every detail so parts of your geometry can be defeatured, which means removing those details to save time.įor example, your product may have a name plate attached. Many times, CAD geometry is very complex and detailed for manufacturing purposes. When using FEA simulation software, such as Mechanical, it’s important to determine what features from your CAD model need to be meshed and what features don’t.

How to Prep your CAD/Geometry for Meshing Meshing is the process of turning irregular shapes into more recognizable volumes called “elements.”īefore you start meshing, you must first upload a geometry or CAD model into, for example, Ansys Mechanical to begin the simulation process. An FEA solver cannot easily work with irregular shapes, but it is much happier with common shapes like cubes. A mesh is made up of elements which contain nodes (coordinate locations in space that can vary by element type) that represent the shape of the geometry. Meshing is one of the most important steps in performing an accurate simulation using FEA. FEA has matured and has been democratized so that it can be used both by design engineers and specialists. A general technique like FEA is a convenient method to represent complex behaviors by accurately capturing physical phenomena using partial differential equations. In several situations, product behavior in the real-world cannot be approximated by simple hand calculations. Finite element analysis (FEA) is a mathematical representation of a physical system comprising a part/assembly, material properties and boundary conditions.
