Bug Fixes

  • RLS-19: When using the guideline RLS-19, the reflection condition of RLS-90 was used up to now. This error has been corrected with version 2021 MR2, so that the reflection condition of RLS-19 is now used.
  • When converting a traffic source to an industrial source or when using "Long Straight Road" conversion of sound power level corrected.
  • TNM: Screening for cylinder and self-screening corrected.
