Is your feature request related to a problem? Please describe.
Gravitational acceleration component is not included in the local blade flapwise and edgewise accelerations (e.g. Spn9ALxb1 , Spn9ALyb1). The blade (structural) accelerations are computed relative to the inertial frame; they do not include the gravity effect. This true for both Elastodyn and BeamDyn.
When comparing measured accelerometer data from wind turbine blades to OpenFAST simulations, it would necessary to include the graviational acceleration component as they are physically present in the field measurements.
Describe the solution you'd like
As an option, output the accelerations including gravity.
Describe alternatives you've considered
Let the user define the frame of reference overwhich they desire to output the blades acceleration signals.
Additional context
N/A
