You can create or edit Free Body Diagrams (FBD) using several tools that display in the tab area. Each FBD tool displays on a separate tab, which opens when you activate that tool.
Free Body Diagram (FBD) utilities facilitate the extraction and post-processing of grid point force results. FBD extractions are typically utilized for breakout and/or sub-modeling analysis schemes, where balanced "free body" sub-cases are extracted from a coarse grid model and applied to a fine grid sub-model for eventual optimization and/or analysis. FBD is also used to extract cross-sectional resultant forces and moments (typically at the centroid of a cross-section) for use in traditional strength calculations.
