Flexible Body Mode Filter

Right-click flexible body → Modify (shortcut: Double-click) → Mode Filter

Lets you select a filter type to remove modes from the animation display. By default, all enabled modes are used to generate nodal displacements for each flexible body during animations. To increase animation performance, Adams Flex has three filters that let you remove graphically insignificant modes for animations. A mode that is filtered out is excluded from the modal superposition and any contribution to the deformation of the body is ignored. Note that these modes are not filtered out for numeric operations, such as signal processing or xy plotting.

For the option:	Do the following:
Flex Body	Enter the name of the flexible body.
Filter Modes By	Select one of the following: ■None - Includes all modes for computing the graphics display. ■Frequency - Excludes any mode that is activated above the specified frequency. ■Min Displacement - Excludes any mode that does not contribute the minimum displacement specified for at least one vertex of the flexible body. For example, if you are viewing the animation of a vehicle driving down the road, it is unlikely that you would be able to see deformations of 0.5 mm or less. Therefore, if you set a mode filter value of 0.5, any mode that contributes less then 0.5 is considered insignificant and is ignored for animations. This calculation is performed at each frame of the animation, allowing the set of significant modes to change throughout the simulation. ■Percentage - Determines the maximum displacement contributed by all modes, and excludes any mode that doesn't contribute displacement of one vertex at least as significant as a percentage of the maximum. For example, setting the percentage filter at 15% excludes any mode not contributing at least 15% of the most dominant mode. This calculation is performed for each frame of the animation, therefore, allowing the set of significant modes to change throughout the simulation.
Filter Value	Enter the frequency, minimum displacement, or percentage for the specified filter.
