Pre-meeting stakeholder’s reports

Working on different papers for the ditital twin track of Isola 2020
Progressed the different MADE FAST part projects involvement of digital twins
Gave up on the digital twin plan with Terma for now
Supplied digital twin feedback for a Danish paper on digital twins (see https://ipaper.ipapercms.dk/TekniskLandsforbund/teknikeren-2020/teknikeren-032020/?page=18#/)

Completed near-final draft of ISoLa 2020 paper with Peter, Cláudio, and Hugo.
Working on a new research proposal for Digital Twins: UK EPSRC’s Centre to Centre programme.

Finally got some decent calibration results out of the UR3E Robot (torque equations only).
Working on Isola 2020 paper
Misc FMI-standard tasks.

Have still been working on writing testing procedures of INTO-CPS app.
Reviewed WATEC presentation made by Hugo regarding Aarhus Vand Digital Twin Project.
found that the download manager of the latest INTO-CPS App downloads a 20-sim version 4.8.1 that exports broken FMUs. So, I updated the new version (4.8.2) of 20-sim in downloads.
have been working on converting states from the TLA+ model checker into states for the rabbitmq fmu.

Made some progress with the FMI3 API model, as well as some updates to the static semantics as the FMI Standard is being changed.
Fixed conditional breakpoints, hit counts and tracepoints in the LSP server, so you can now stop conditionally, stop when the break hitcount is =, >, >= or a multiple of some number, and “trace evaluate” expressions as the tracepoints are reached, without stopping.
Raised some problems with the (new) Reference FMUs defined in the FMI Standard repository, both for FMI2 and FMI3.
Made a couple of Overture fixes, following from bugs raised by Fuyuki Ishikawa.
Had a quick look at some Maestro user documentation.
Reviewed an ACM Survey document.

Fixed a couple of issues of Overture. I am currently looking at longstanding issues caused by several deprecated APIs. I hope this will fix the Debug Perspective layout problem.
First development cycle of tests for the INTO-CPS App reached full coverage of Tutorials 1 to 11. The Work will be presented on the 29th, and Armine is on “study for exams vacation” leave until then.
Helped Kristoffer solve a INTO-CPS settings loading problem forcing the user to delete the json file to be able to launch the app. Working on a close project button feature, which is intersting regarding testing purposes.
Worked with Hao on a DSE approach to compute tolerable delays in a refinement of the LFR model.
Contributed to the Isola Tolerance Paper.

Fixed overture-FMU such that it works on mac catalana. Also updated internal dependences.
Fixed rabbitmq-fmu, such that it is cross-platform. Needs documentatino and needs linux testing. Needs to be checked with tla model.
Working on wrapping robotti within an FMU. Sanity check has been conducted and compilation is ongoing.
Working on Maestro 2. Can run co-simulation. Executed new performance test - good results again.
Simon Hansen is working on new initialization plugin

Cleaning up PyFMU for Hubcap presentation later this month.
Moving logic from wrapper into Python
- Easier to extend and maintain
- No memory leaks
Cross platform C/C++ + Third party libraries are a pain in the butt
- Exteremely brittle on Windows.
Experimenting with Rust language
- has bindings for python.
- built in package manager and cross platform build.
- definitly a more pleasant development experience.
