Feature or improvement description
When converting AeroDyn to use the FileInfoType for file parsing with PR #643, the primary input file reading was split from the
ReadInputFilesroutine. The value forDTAerois then read withParseVarWDefaultto populateInputFileData%DTAero. However, thisDTAerowas getting overwritten during at the beginning of theReadInputFilescall with theIntervalpassed from the glue code. The result wasDTAerofrom the input file was always replaced with the glue code timestep, so sub-cycling could not occur.This affects all OpenFAST versions from 3.0.0 until now.
