Inertia Relief in Nastran
Choosing the correct boundary condition is an important step of running a FEA analysis. But what if the correct boundary condition is no constraint at all? An aircraft in flight is in a state of static equilibrium. The aerodynamic forces on the vehicle are balanced out by inertial forces. Adding a constraint would not accurately model this problem. That’s why we use Inertia Relief when analyzing full vehicle models. Inertia Relief balances out the applied loads with equal and opposite accelerations, creating a state of static equilibrium and eliminating the need for constraints. Nick Mehlig from Structures.Aero covers topic of Inertial Relief in NX Nastran, including: • What is inertia relief? • Setting up a static analysis with inertia relief in FEMAP • Recovering OLOAD data from Nastran output What was added and changed in the latest version of Femap (Version 12)? Andrew shares all the new updates to Femap 12 including visualization improvements, geometry break at intersections, automatic rigid element update when meshing, data mapping, and more. We keep track of changes to Femap in our Femap Change Log: https://structures.aero/software/fema...
