Running Modelica using Docker

In a terminal on your Mac, run:

ip=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}') 
Xhost +$ip 
docker run -it -v ~/.Xauthority:/root/.Xauthority -e DISPLAY=$ip:0  openmodelica/openmodelica:v1.20.0-gui /bin/bash

Source: Docker instructions, which also had the commands for linux:

docker run -it --rm -e "HOME=$HOME" -e "DISPLAY=$DISPLAY" --network=host --user "$UID" -v "$HOME:$HOME" -v "$PWD:$PWD" -w "$PWD" openmodelica/openmodelica:v1.20.0-gui
