Comments

  1. In OptiStruct 13.0 the new and improved ACMODL formulation will couple the fluid grids at the interface to only a single layer of structural grids. This parameter can be used to restore the formulation used prior to 13.0. The old formulation coupled the fluid face to every structural grid in the search box.
