GREAT-ER 1.0 Update to 1.0.5: Installation: - Extract the contents of the zip-archive into your GREAT-ER 1.0 directory to update to the new version. - Confirm all requests to overwrite existing data. - Reboot the PC after installation. - After reboot, start GREAT-ER 1.0 as usual. Check the update: - The inital screen displays GREAT-ER 1.0.5 - Model info (Menu GREAT-Help / About Model) displays: GREAT-ER Simulator version 1.0 (27 JAN 2003) Rationale: The versions of the GREAT-ER 1.0 Simulator (up to version 1.0 (16 FEB 2000) contain a bug in the module for Activated Sludge, Mode 2/3: Elimination was effectively calculated always to zero. The current version (Version 1.0 (27 JAN 2003)) fixes this bug, i.e. the code implemented for the Module during the GREAT-ER 1.0 project is now activated to calculate elimination rates based on the SimpleTreat Model for activated sludge plants. The correctness of the results was not further analysed during activation, but the model output was analysed by the original author (Geert Boeije) in his PhD thesis: http://www.great-er.org/files/Boeije (1999).pdf It was ensured that the activation has no side side effects on other model modes. The validated results of mode 1 simulations were compared for different simulator versions. Intevation GmbH, 2003
