Flexible Body Export Options dialog box

Modeling Object
Name	Specifies the name of the flexible body option object.
Label	Specifies the label for the flexible body option object.
Properties
File Format	Specifies the output file type that the software generates for the flexible body.RECURDYN — .rfiADAMS — .mnfOP4 — .op4MATLAB — MATLAB script fileSimcenter 3D Motion — .op2
Equation Type	Appears only when File Format is set to RECURDYN, ADAMS, OP4, or MATLAB.Specifies how the equations are used. STANDARD — The matrices are based on standard second order differential equations of motion. STATESPACE — The matrices are based on first-order differential equations that represent the equations of motion, and are suitable for use with control system software.Available when File Format is set to OP4 or MATLAB.
Recovery	Appears only when File Format is set to RECURDYN, ADAMS, OP4, or MATLAB.Specifies whether data recovery runs after the creation of the output file.YES — The software creates the output file and runs data recovery.NO — The software only creates the output file.
Mass Invariant	Appears only when File Format is set to RECURDYN or ADAMS.Specifies how the software computes the mass invariants.PARTIAL — For RecurDyn, does not compute mass invariants 6 or 8. For Adams, does not compute mass invariants 5 or 9.CONSTANT — For RecurDyn, computes mass invariants 1, 2, 3, and 9. For Adams, computes mass invariants 1, 2, 6, and 7.FULL — Computes all mass invariants.NONE — Does not compute any mass invariants.
Element Geometry	Appears only when File Format is set to RECURDYN or ADAMS.Specifies a set of elements whose connectivity is exported to the output file.All Elements (NONE) — The software does not use the connectivity of specific sets; it writes all grids, geometry, and associated modal data to the output file.All Element Sets (ALL) — The software uses the connectivity of all element sets to export face geometry.Group — Allows you to select a specific element set whose connectivity is used to export face geometry.
Group	Appears only when Element Geometry is set to Group.Select the element set whose connectivity you want to use to export face geometry.
New group	Appears only when Element Geometry is set to Group.Lets you create a new group.For information on groups, see Groups.
More options	Appears only when Element Geometry is set to Group.Lets you search and filter on the list of groups.
Options
Appears only when Element Geometry is set to Group and you click More Options .
Find	Lets you search for a group by typing a group name and clicking Find . The results appear in the group table below.
Filter by Name	Filters the list of group names.Type an asterisk (*) and press Enter to match all names.
Group table	Lets you select a group from a list.
