QDDOT
The QDDOT() function returns the modal acceleration for the requested mode (m_id) for the flexible body specified (f_id). This function can be used in your model as a valid MotionSolve expression.
Format
QDDOT(f_id, m_id)Arguments
- f_id
- The ID of the flexible body in the model.
- m_id
- The mode ID whose acceleration is requested.Note: m_id > 6, that is, the expression is only supported for non-rigid body modes.
Example
<Post_Request
id = "2"
type = "EXPRESSION"
label = "Modal displacement"
expr2 = "QDDOT(30102,7)"
expr3 = "QDDOT(30102,8)"
expr4 = "QDDOT(30102,9)"
expr6 = "QDDOT(30102,10)"
expr7 = "QDDOT(30102,11)"
expr8 = "QDDOT(30102,12)"
