BREAKOUT MODELING (Global-to-Local Analysis ) with FEMAP & NX Nastran

Breakout modeling is a Finite Element technique of FEMAP that allows you to evaluate stresses for a portion of an overall model. In breakout modeling, you: • Analyze the overall structure, using a coarse mesh, and then solve for displacements. • Create breakout models and critical stress locations using a fine mesh. • Map the displacement results from the overall model to the cut faces of the breakout model. • Solve the breakout model and evaluate stresses. Breakout modeling uses ==================== You may want to use breakout modeling for the following reasons: • Creating a fine mesh of an overall structure can be very expensive in terms of performance and hardware requirements, especially for nonlinear analysis. • Large, fine meshes can significantly increase turnaround times for variants and model changes. • Stress evaluations must be done with existing (coarser) models. • It is difficult to refine critical areas in advance because not all critical locations are obvious.
