Known bugs in version 11.0d


  • In previous versions the QTF data relating to the quadrature zone, outer circle and asymptotic zone were editable when no mesh file was supplied for the panelled zone. This was incorrect because, in models with no panelled zone mesh file, these data items are not used.
  • Models that include sum-frequency QTFs may have raised a floating point overflow error message during validation. The error was most likely to occur in the first stages of model building, because it only affected models in which all the waves periods equal zero.

This bug will be fixed in version 11.0e.
