QDOT

The QDOT function returns the first time derivative of the modal coordinate for mode number mode_number of FLEX_BODY/id.

Format

QDOT(id, mode_number)

Arguments

 
id
The identifier of the FLEX_BODY.
mode_number
The mode whose modal coordinate data is requested.

Example

MFORCE/20,FLEX_BODY=6,CASE_INDEX=1,SCALE=QDOT(5,10)
In this example, a modal force, whose loadcase is scaled by the first time derivative of the modal coordinate corresponding to mode number 10 on FLEX_BODY/5, is defined.
