We might have closed this too soon... The previous plots had AD15 turned off. When I turn it on, with the airfoil unsteady aero turned off (AFAeroMod=1), I do see...

If I zoom in in the first plots, the asymmetries are still there indeed. I will now run a case without gravity

Things seem to stay symmetric for the no gravity / no aerodynamics case (https://github.com/ptrbortolotti/debug_BD_bladesymm/tree/master/BDstruct_nograv)  @andrew-platt could you please check on your end?

I've just checked the blade asymmetry issue in the IEA15 RWT comparing old results with newer ones generated using the qfit=6 beamdyn model implemented in https://github.com/ptrbortolotti/openfast/blob/7ac7a03b628bcee244a97d8e2e1a93e13d3026ee/modules/beamdyn/src/BeamDyn.f90#L566 The case has gravity...

The plot might not be zoomed in enough, but rotations with order element 10 are consistently off by 5e-4, whereas they are machine-precision identical with order element 14

Hello, yes that, combined with an order_elem=10, should fix the issue. Please let us know if that is or isn't the case. Pietro

hello Rick, we might need to loop back @evan-gaertner into this because I'm struggling to justify all the rotations and normalizations that are applied. What I see is that here...

I can reproduce the error, I'll work to fix it asap

I'm afraid it will take a wisdem release to fix this. @gbarter and I will work on this

@yonghoonlee , if you can, please try this WISDEM branch https://github.com/WISDEM/WISDEM/tree/compare_designs
