About the Patch
This patch upgrades your GateCycle 5.3x installation to version 5.34. You must have GateCycle version 5.3x installed to use this patch. This patch does not affect your current GateCycle copy protection, and it supports both the software-based (Crypkey®) and the hardware-based (Hardlock) copy protection systems.
Terms and Conditions
Only organizations with a current maintenance contract for GateCycle software with GE may legally download and apply the patch software. All licensing arrangements previously signed remain in effect with this upgrade. This patch software is provided as a courtesy to our customers. Version 5.34 is not a major release, so it will not be sent automatically to all of our maintenance customers.

GateCycle Version 5.34 Major Bug Fixes
1. Mixer, Gtcomb, Flash, Evcool: Corrected energy balance errors triggered by improper mixing of 2 phase steam and gas streams.
2. Steam turbine: Corrected convergence problems caused when initial bowl pressure is less then the outlet pressure.
3. Pump: Corrected UOM error on exit pressure difference method that led to incorrect pump exit pressure for nonzero pressure difference values.
4. Fossil and Fluidized Bed Boilers: H-C Ratio is now passed out for the flue gas stream when these icons are used as gasifiers.
5. Mixer: Added convergence check to catch demand flow error caused by more inlet flow than demanded flow.
6. Electric Chiller: Corrected property error triggered when inlet air is below freezing.
7. Fluidized Bed Boiler: Corrected descriptions of the off design boiler feedwater methods.
8. GTDATA + GT: Inlet Air molecular weight and H2O mole fraction values are now accessible from macros.
9. Real Gas Properties: Corrected unitialized variable problems in the Peng Robinson and Soave - Redlich - Kwong methods.
10. General GUI: Invalid characters in model and case names are now caught in all situations.
11. Component Data display icon: Corrected flowsheet save bug that prevented changes made to an existing component data icon from being saved.
12. Flash Tank, Aux. Boiler: Linked Duty (heat transfer) method now works with external models and case and current model and case references.
13. Gas Source: The relative humidty of an air source can now be accessed from a macro.
14. Source: A warning is now generated when a pressure signal arrives at a linked source if the pressure signal and linked pressure are different.
15. System Diagnostic Audit: Version number on the Triage dialog is now 5.34 and error messages about missing templates are gone.
16. Splitter: The damping factor for pressure based split up port method is now read properly thereby preventing convergence problems.
17. Help file: minor changes.
