Topics • What is Finite Element Analysis? • What comprises a FEA model? • Femap Modeling Process Flow • Femap Model Objects and Commands femap101-g-v10.1.1 Fermp 101 1 - 1 Introduction to Femap with NX Nastran Student Guide Lesson 1 The FEA Modeling Process Using Femap A Finite Element Analysis (FEA) is a mathematical simulation of a physical structure when internal and external forces are applied to it. It can be used to simulate the following types of physical behavior: What is Finite Element Analysis? • Structural • Thermal • Fluid Flow • Optical • Electromagnetic Femap can be used to model the first four types of FEA models. femap101-g-v10.1.1 Femap 101 1 - 2 Introduction to Femap with NX Nastran Student Guide Lesson 1 The FEA Modeling Process Using Femap A Finite Element Analysis model is a collection of: • Finite Elements - well-defined mathematical models of: • Beams and Rods S f Sh ll l t What comprises a FEA model? • Surface or Shell elements • Solids (Tetrahedral or Hex) • Miscellaneous elements such as Springs, Mass, Rigid, and Contact • Material attributes • Boundary conditions (loads and constraints) femap101-g-v10.1.1 Femap 101 1 - 3 Introduction to Femap with NX Nastran Student Guide Lesson 1 The FEA Modeling Process Using Femap A FEA model is at best, an approximation of a physical structure. The accuracy of the results from a FEA model are only as good as the quality of the mesh and the accurate application of material attributes and boundary diti t d l Takeaway conditions to a model. femap101-g-v10.1.1 Femap 101 1 - 4 Introduction to Femap with NX Nastran Student Guide Lesson 1 The FEA Modeling Process Using Femap Femap Objects and Workflow for Generating a FEA Model Geometry Materials Boundary Conditions • Constraints Properties • Loads Mesh Analyze Postprocess femap101-g-v10.1.1 Femap 101 1 - 5 Introduction to Femap with NX Nastran Student Guide Lesson 1 The FEA Modeling Process Using Femap Import Geometry Create Geometry Modify Geometry File, Import Geometry Geometry commands Geometry, commands Geometry y File, References Geometry, commands y Modify, commands Direct CAD geometry interfaces  Solid Edge, NX (Unigraphics and I- deas) ProE CATIA and deas), ProE, CATIA, and SolidWorks.
