Modelica Working Group online. If anyone wants to develop a new image for the landing page reach out to Ettore. Check if you are included among the participants, if not fill the Google Form and Ettore will add you. If you have a publication or an application abstract that you want to add reach out to Ettore to add it.

Expert meeting at Modelica conference 2023

Possible idea for social event on Wednesday night (last day of the conference), open to modelica working group/BOPTEST people New Proposal program for the workshop: Thursday the 12th of October BOPTEST meeting from 9 a.m. to 11:30 a.m. Lab Tour 11:30 a.m. 12:30 p.m. Lunch 12:30 p.m. – 1:30 p.m. IBPSA Modelica Working group meeting 1:30 p.m. to 4/5 p.m.

Ettore sent google form asking -Number of partecipants (for Wed and Thu) -Need for parking (for Thu) -Leaving time (on Thu,mainly for BOTPEST meeting)

Modelica Conference Trainings Workshop

Michael proposed to make only one Modelica library workshop around IBPSA (instead of one for each library). The potential layout could be as follows:

  • IBPSA current uses in research and industry.
  • Simple examples using IBPSA Modelica models (It will be done using OpenModelica), (Filip has documentation to share) https://github.com/open-ideas/__CrashCourse__/blob/master/Exercises/Exercise%202/Latex/Exercise2.pdf, Volunteers to update the documentation and add intermediate models can reach out to Ettore or Michael (Dre volunteered so far and also they could be the lead in conducting the training part of the workshop). Furthermore, there should be a representative for each library and someone from Open Modelica.
  • End of training the different Modelica libraries can be introduced, each with an feature highlight

Michael made application (Fabian confirmed spot, formal confirmation will arrive in mid August)

ATES model

Update from Alessandro: currently working on the development of a two-well ATES model, which consists of a warm and cold well. Circulation pumps are included in the model, which exposes input connectors for controlling the water flow rate. Moreover, a multiplier is used to scale up the capacity of the aquifer, accounting for multiple warm and cold wells.

ISO 13790 models

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)

PV collector, battery and electrical component models

One pull request ready. Still have an issue with time shift in validation data (hopefully done by end of the week)

Modular heat pump

https://github.com/ibpsa/modelica-ibpsa/pull/1628.

Casper did final review, going to meet with Fabian on Thursday. Discussion regarding package structure. Michael, suggested to use Move class script

New state selection

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.
