What is new
Highlights in 1.2
Improved algorithms increase the simulation robustness and speed.
Compressed binary file format
The default option is now to save the entire IDA Tunnel project in one single binary file. This makes it easier to copy IDA Tunnel projects and to incorporate them in file handling systems.
Numerical debugging and performance
When the schematic is visible during simulation the slowest converging component is shown in red each time step. With this feature, problematic component models are more easily detected.
Your IDA Tunnel project is now automatically saved every 10 minutes, and before and after each simulation.
IDA now supports Unicode - names in, e.g., Mandarin can be handled.
Running multiple sessions
Start additional IDA Tunnel sessions from the file menu. In this way you can work on several sessions in parallel, both during modelling and during simulation.
Support in tables for copy/paste of multiple cells.
General improvements and bug fixes
Highlights in 1.1
Improved algorithms increase the simulation execution speed - in many cases simulations run up to 30 % faster.
Version handling system
A version handling system keeps track of model changes and automatically reruns all cases that depend on a change. Differences between models are computed as scripts and results between cases are easily compared.
More advanced paths and train routes
New climate file download center
A new download center makes it easy to select the weather files and design data that you need. More than 3 000 worldwide weather files are now available for direct download and use in IDA Tunnel.
New features in the visualization kit:
Improved energy calculation
Emissions and heat
The Simulation Minute Tokens (found in previous IDA Tunnel versions) have been removed, allowing for unlimited simulation usage. Together with the new dormant license system (where the rental period can be paused, e.g. between projects), you can now make more efficient use of your IDA Tunnel license than before.
