[Bldg-sim] IDA ICE experience

Hello there,

I started using IDA ICE for my master thesis two years ago, for which I 
had to model a complex HVAC system for a museum (several ventilation 
systems for cooling/heating+drying/humidifying with 2 central heat 
recovery systems, rooms with contaminated air, different control 
strategies with variable airflows...) Though the whole system became 
quite complex in the end it was still possible to keep on working well 
with the models and optimizing the control strategies using the features 
of the integrated model versions comparator.

As Chris Yates already explained, it is possible to get into the 
mathematical background of every components of the model. You can also 
plot every variable that you find there, so you can really interrogate 
what happens in the model.

Furthermore there are some great other tools like loading different 
models and getting a "difference check", which is pretty useful while 
debugging, or also starting an additional session with an independent 
Core, so you can keep on working on an other model while already running 
another simulation.

The results can be well exported and in different ways if needed.

Regarding the geometry I found the combination of the 3D interface with 
the floor plan interface quite good. Importing schemes from IFC, 
Sketchup or DWG worked well too.

Important to mention as well is the help from EQUA: mail, phone, 
webinars (free), seminars (not free), also the users forum can be very 
useful. Since I have been using IDA ICE I could always find a way to 
solve the problems (debugging or modelling).

As a user I find it also great that there are so many possibilities to 
explore, so many things to model, to connect and to simulate, you have 
the feeling you are learning a lot while working, but this is something 
which is common to any good software...

Last but not least: there is an integration of OpenFOAM which is 
coming,... currently it is still a beta-version but I already saw it 
working, quite impressive.

I don't have that much experience with other softwares so I can not 
really compare objectively. I can only say: go for a trial or/and ask 
for a live-demo and judge by yourself!

Greetings from Berlin
