Highlights in 1.1

Below is a list of of the most important news in IDA Tunnel 1.1.

Faster simulations

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 procedure for defining route paths, and heating and cooling pipes.
New procedure for defining path reports.
Trains can now change the direction (at platforms only), and pass the same location several times.
Paths can now be edited.

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.

Diagram functions

New features in the visualization kit:

Carpet plots (color-coded variables) support pattern recognition.
More options for the duration diagram, e.g. display time over or under a certain limit.

Improved energy calculation

Improved energy reports.
New energy categories added: heating and cooling.
New diagram showing all variables contributing to the energy report.

Improved models

Calculation of heat from fans is now possible.
A heat exchanger model has been added.
Small improvements in several other models.

Emissions and heat

PIARC 2012 emission tables have been added.
Heat emission from road traffic has been added.

License improvements

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.
