Edgewise and flapwise deflections and moments not showing

[FannyICY]

Hello everyone.

I'm running simulations of the IEA 22MW with OpenFAST, with a mean turbulent wind speed of 6mps. I also set the DOF as follows

True FlapDOF1 - First flapwise blade mode DOF (flag)
True FlapDOF2 - Second flapwise blade mode DOF (flag)
True EdgeDOF - First edgewise blade mode DOF (flag)
False TeetDOF - Rotor-teeter DOF (flag) [unused for 3 blades]
False DrTrDOF - Drivetrain rotational-flexibility DOF (flag)
True GenDOF - Generator DOF (flag)
False YawDOF - Yaw DOF (flag) True TwFADOF1 - First fore-aft tower bending-mode DOF (flag)
True TwFADOF2 - Second fore-aft tower bending-mode DOF (flag)
True TwSSDOF1 - First side-to-side tower bending-mode DOF (flag)
True TwSSDOF2 - Second side-to-side tower bending-mode DOF (flag)
False PtfmSgDOF - Platform horizontal surge translation DOF (flag)
False PtfmSwDOF - Platform horizontal sway translation DOF (flag)
False PtfmHvDOF - Platform vertical heave translation DOF (flag) False PtfmRDOF - Platform roll tilt rotation DOF (flag) False PtfmPDOF - Platform pitch tilt rotation DOF (flag)
False PtfmYDOF - Platform yaw rotation DOF (flag)

I'd like to output edgewise and flapwise deflections of the blades using the following output names.

"TipDxb1" - Blade 1 flapwise tip deflection (relative to the undeflected position)
"TipDyb1" - Blade 1 edgewise tip deflection (relative to the undeflected position)
"TipDxb2" - Blade 2 flapwise tip deflection (relative to the undeflected position)
"TipDyb2" - Blade 2 edgewise tip deflection (relative to the undeflected position)
"TipDxb3" - Blade 3 flapwise tip deflection (relative to the undeflected position)
"TipDyb3" - Blade 3 edgewise tip deflection (relative to the undeflected position)
"RootMxb1" - Blade 1 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMEdg1" - Blade 1 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMyb1" - Blade 1 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root
"RootMFlp1" - Blade 1 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root
"RootMxb2" - Blade 2 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMEdg2" - Blade 2 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMyb2" - Blade 2 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root
"RootMFlp2" - Blade 2 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root
"RootMxb3" - Blade 3 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMEdg3" - Blade 3 edgewise moment (i.e., the moment caused by edgewise forces) at the blade root
"RootMyb3" - Blade 3 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root
"RootMFlp3" - Blade 3 flapwise moment (i.e., the moment caused by flapwise forces) at the blade root

The problem is that my plots show that these edgewise and flapwise values are constantly 0, which I doubt. On top of that, pyDatView recognizes them as "NVALI".

The OpenFAST simulation took 12 hours approximately with the following messages.

Is there any bug, change or update regarding the outputs of this new model? If not, could you help me output edgewise/flapwise deflections and root bending moments of blades, please?

Thank you!

Best regards.
