Define Objects: Components

Define Objects: Surfaces| Volumes| Components| Bodies| Forces

Components group surfaces and/or volumes into logical sets; as such, components may be viewed as "containers" for surfaces and/or volumes. The main purpose of components is to allow the user to group these entities and specify properties for the group as a whole. Components themselves may also be grouped into bodies.

Another potential use for components is to generate force/moment reports for specific sets of surfaces. For each component specified, the solver generates a forces.Comp.ComponentName file which contains the summed forces and moments on all surfaces that make up the component. The center of gravity specified for the component is the CG used to compute moments for all surfaces in a given component. NOTE: if a component is part of a body, the center of gravity is inherited from the body; any specified CG for the component is ignored.
