This repository contains a water-tank model swap experiment for DTaaS. The experiment uses the Maestro co-orchestration engine for FMI-based co-simulation with the Model Swap feature including a FaultInject extension. The repository is a Docker-less version of the experiment at https://github.com/lausdahl/fmiSwap for use on the DTaaS platform.

The model swap mechanism demonstrated by the experiment is detailed in the paper "Dynamic Runtime Integration of New Models in Digital Twins" [H. Ejersbo, K. Lausdahl, M. Frasheri, L. Esterle] presented at the SEAMS 2023 conference. The water-tank experiment is further detailed here: https://arxiv.org/abs/2304.07328.

git clone [email protected]:hejersbo/dtaas-wt-swap.git <WORKSPACE>

or if folder structure already exists and is non-empty:

cd <WORKSPACE>
git init
git remote add origin <this-repo-url>
git pull
git checkout main -f
git branch --set-upstream-to origin/master

cd <WORKSPACE>/digital_twins/water_tank_swap
./wt-run.sh
./post-process.sh

The post-process.sh runs an experiment specific python plot of outputs. Plot results are in folder post.

If not already installed on the DTaaS platform, maestro requires the Java JDK 11 to be installed:

sudo apt-get install openjdk-11-jdk

In addition, these python packages are needed for post processing:

pip install pandas matplotlib
