Resolved Issues

  • More than one line in *DATABASE_TRACER is now supported.
  • Curves attributes OFFA and OFFO are now considered in unit conversion process.
  • Include files defined in INCLUDE_TRANSFORM are now correctly exported in the folder defined by INCLUDE_PATH.
  • Attribute IDGRP in *DEFINE_ELEMENT_DEATH_(OPTION) is now correctly supported as an integer.
  • A correction has been made in the model import process when a model has an INCLUDE_TRANSFORM referencing an undefined include file.
  • Constraint entity IDs offsets, defined with IDROFF in INCLUDE_TRANSFORM, are now correctly applied.
  • A correction in the model import process for *INITIAL_STRESS_BEAM which were failing in some use cases has been made.
  • A correction in the model export process when option DBOX is defined in *SET_SEGMENT_GENERAL has been made. The option DBOX wasn't always exported correctly.
  • A correction in the model import process for *INCLUDE_TRANSFORM with IDs Offsets referencing nested include files has been made.
