QDOT

The QDOT() function returns the modal velocity 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

QDOT(f_id, m_id)

Arguments

f_id
The ID of the flexible body in the model.
m_id
The mode ID whose velocity 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            = "QDOT(30102,7)"
     expr3            = "QDOT(30102,8)"
     expr4            = "QDOT(30102,9)"
     expr6            = "QDOT(30102,10)"
     expr7            = "QDOT(30102,11)"
     expr8            = "QDOT(30102,12)"
