Michael will come out with an outline to be shared. Each library could have a paragraph/page to show those integrated simulations.
Received a first set of simulation results from TU Delft to start the validation process. They used the tool SEAWAT. The idea is to define a few simulation scenarios and compare the simplified Modelica model with SEAWAT. Work in progress.
Alessandro finalized the PR, Jelger will find some time to review. If he cannot Louis and Lucas can chip in.
No updates.

Michael work on model initialization? Difference of pressure instead of absolute pressure (in theory is better, in numerical simulation it seems inconclusive it depends on the models, scaling seems to work better) Comparison speed vs accuracy? (speed and if models actually run). Maybe use bounded attribute of real variables.
OCT has been updated and it is a work in progress.
PR merged, moved to IBPSA.
New models to be developed/integrate:
- Discussions about others and future development, such as
- APPROVED
- enthalpy and energy recovery wheel (Oakridge national lab is working on a model for the Buildings that could be integrated)
- validation of models (No updates)
- CDL integration (No updates)
- preconfigured controls (No updates)
- NEED MORE DISCUSSION
- NEW: Zoned borefields (https://github.com/lbl-srg/modelica-buildings/pull/3812)
- thermal storage (No updates)
- better dynamic ground coupling of long district pipes (PR merged into Buildings, to be moved to IBPSA)
- CHP and organic Rankine cycle (Casper is working on a PR for Buildings library)
- more geothermal (horizontal loop, slinky loop, others) (Massimo could look into specific modelling efforts that have been done by co-workers)
- APPROVED
Kick-off meeting in November.
If interested in an advisory board work with Oliver Lenord to issue NDA contract.
Come up with requirements:
data source
large models (compilation, simulation, optimization, UQ)
provide library of models
computationally expensive ones
numerically problematic ones (see also https://ibpsa.github.io/modelica-challenge-problems/)
