Feature or improvement description
This new implementation moves the initialization of the low-pass-filtered potential-flow body positions for
ExctnDisp=2
out of the glue-code and intoHydroDyn_Init
. The initial platform offset fromInit%OutData_ED%PlatformPos
is copied toInit%InData_HD%PlatformPos
for HD initialization. This is more consistent with the OpenFAST modular structure and should help avoid some problems with tight coupling in the future.This updated implementation should fix several issues:
ED%y
is no longer modified inFAST_InitializeAll
to avoid problems with tight coupling.SmllRotTrans
is replaced withEulerConstructZYX
to support large platform rotation.Related issue, if one exists
This PR is a reimplementation of PR #2341 to address the issues raised in PR #2421 based on the discussions with @bjonkman and @andrew-platt.
Impacted areas of the software
Glue code, HydroDyn
