Model was merged
Models are now merged: https://github.com/ibpsa/modelica-ibpsa/pull/1627
Alessandro Updates : BESTEST results have been updated. Still working on the Python file that generates the plots automatically (I have been in touch with Jianjun)
Prioritizing work on ATES. Only update is implementing the g faction as function of sun direction. Probably after Christmas. Michael says to control previous reduce order model based on EN.
One pull request ready. Paper presented. No updates since pull request comments, work in progress.
https://github.com/ibpsa/modelica-ibpsa/pull/1628.
Discussion about signal bus used only for outputs. It will be kept as is and not removed.
https://github.com/ibpsa/modelica-ibpsa/issues/1412
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.
Open discussion points from in person meeting in Aachen:
New models to be developed/integrate:
- Discussions about others and future development, such as
- APPROVED
- enthalpy and energy recovery wheel
- validation of models
- CDL integration
- preconfigured controls
- NEED MORE DISCUSSION
- thermal storage
- better dynamic ground coupling of long (uninsulated) district pipes
- CHP and organic Rankine cycle
- more geothermal (horizontal loop, slinky loop, others)
- APPROVED
OpenSCALING project:
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/)
