Hello,
I have 6x6 mass, damping, and stiffness matrices that represent the linear
model of a helicopter. I'd like to have a single MBDyn node represent a
helicopter, and use the stream file drive for pseudo-realtime input. Once
this works, I'll add slung loads and other nodes/elements.
My question is how to write an MBDyn input file for my single node, state
space model? My matrices have the following format:
Rows: X-Force, Z-Force, Pitch Moment, Y-Force, Roll Moment, Yaw Moment
Columns:
For Mass Matrix: U-dot, W-dot, Q-dot, V-dot, P-dot, R-dot
For Damping Matrix: U, W, Q, V, P, R
For Stiffness Matrix: X, Z, Theta, Y, Phi, Psi
An example Elements Block would be very helpful.
Thank you,
Doug
