• Redesign of the architecture of the calculation kernel of KULI, ensuring full and consistent 64bit support as well as better memory handling and system stability
• Extension of the dynamic solver, in particular the parallel flow cooler and oil circuits are now supported, initial temperatures of tubes and circuits can be set via actuator, etc.
• Reduction of the calculation time based on changes of user defined formulas in the calculation controller, logging mechanism, and the kind of calculation of material properties
• Support during opening of scs-files with the option to automatically unpack missing components
• Quickly find sources of a signal receiver via context menu.
• Additional sensors and actuators for passenger compartment and EXV
• Additional refrigerants R290, R32, R454c and R410a based on NIST standard
• Easier selection of results in the project tree of KULI lab with the help of a filter
• Possibility to change the units given in axes of 2D charts in KULI lab
• Enhanced message and error logging mechanism

KULI 13.1 includes:

• Complete revision of AC solver: The AC solver has undergone a complete revision with the following benefits: 
  • Better stability 
  • Support of more configurations 
  • Better detection of problems caused by questionable data.
  • In addition a lot of hints have been included in order to assist the user in finding the cause of incorrect circuit configurations. 
  • The online help has been updated to provide guidelines how to set up valid A/C circuits. 
• COM objects can now be marked as explicit FMU connectors
• Enhanced Messaging regarding status of result file writing
