Direction of input force and moment in stress-strain recovery

[vacupenda]

I would like to know the directions of the six components of the input loads (F1, F2, F3, M1, M2, M3) required for stress-strain recovery for the airfoil, and whether they are in the following positions?

0 0 0
1 0 0 0 1 0 0 0 1
F1 F2 F3 M1 M2 M3

They are arranged as you stated. Their directions align with the beam coordinate system you used for beam analysis.

Got it, thank you. So, if I select according to the following coordinate system, F1 should be along the X1 direction, and so on, right?

[wenbinyu-PU]

Yes.
