An OpenModelica Jupyter kernel

OpenModelica

OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage.

OpenModelica User's Guide

The User's Guide is automatically generated from the documentation repository.

OpenModelica environment

The OpenModelica Compiler is the core of the OpenModelica project. OMEdit is the graphical user interface on top of the compiler. OMSimulator is a capable FMI and SSP-based Co-Simulation environment, available as a standalone version or integrated in OMEdit. In addition there are interactive environments OMNotebook, OMPlot and OMShell interaction with the OMCompiler as well as various other tools: OMOptim, OMParser, OMSens, OMSense_Qt.

Working with the repository

OpenModelica.git is a superproject. Clone the project using one of:

# Faster pulling by using openmodelica.org read-only mirror (low latency in Europe; very important when updating all submodules)
# Replace the openmodelica.org pull URL with https://github.com/OpenModelica/OpenModelica.git if you want to pull directly from github
# The default choice is to push to your fork on github.com (SSH). Replace MY_FORK with OpenModelica to push directly to the OpenModelica repositories (if you have access)
MY_FORK=<MyGitHubUserName>
git clone --recurse-submodules https://openmodelica.org/git-readonly/OpenModelica.git
cd OpenModelica
git remote set-url --push origin [email protected]:$MY_FORK/OpenModelica.git
git submodule foreach --recursive 'git remote set-url --push origin `git config --get remote.origin.url | sed s,^.*/,[email protected]:'$MY_FORK'/,`'

If you are a developer and want to update your local git repository to the latest developments or latest heads, use:

# After cloning
cd OpenModelica
git checkout master
git pull
# To checkout the latest master on each submodule run
# you will need to merge each submodule, but your changes will remain
git submodule foreach --recursive "git checkout master && git pull"

# Running master on all submodules might lead to build errors
# so use this to make sure you force all submodules to the commits
# from the OpenModelica glue project which are properly tested
git submodule update --force --init --recursive

In order to push to the repository, you will push to your own fork of OpenModelica.git, etc. You will need to create a fork of each repository that you want to push to (by clicking the Fork button in the GitHub web interface).

If you do not checkout the repositories for some GUI clients (such as OMOptim.git), these directories will be ignored by autoconf and skipped during compilation.

To checkout a specific version of OpenModelica, say tag v1.16.2 do:

git clone --recurse-submodules https://github.com/OpenModelica/OpenModelica.git
cd OpenModelica
git checkout v1.16.2
git submodule update --force --init --recursive

If you have issues building you can try to clean and reset the repository using:

git clean -fdx
git submodule foreach --recursive git clean -fdx
git reset --hard
git submodule foreach --recursive git reset --hard
git submodule update --init --recursive

To check your working copy status and the hashes of the submodules, use:

git status
git submodule status --recursive

To checkout a minimal version of OpenModelica

git clone https://openmodelica.org/git-readonly/OpenModelica.git OpenModelica-minimal
cd OpenModelica-minimal
git submodule update --init --recursive libraries

Build OpenModelica

• Linux/WSL/OSX Instructions
• Windows Instructions

We automatically generate nightly builds for Windows and for various flavours of Linux. You can download and install them directly if you just want to run the latest development version of OpenModelica without the effort of compiling the sources yourself.

How to run

Here is a short example session. This example uses OMShell-terminal, but OMShell, mos-scripts, or OMNotebook work the same way.

$ cd trunk/build/bin
$ ./OMShell-terminal
OMShell Copyright 1997-2015, Open Source Modelica Consortium (OSMC)

To get help on using OMShell and OpenModelica, type "help()" and press enter

jupyter-openmodelica's Issues

Enable Autocompletion

It would be good to enable autocomplete. There should be a way to make it work via the python interface to OpenModelica, at least it appears that way since there is at least one example of Modelica Autocomplete built using Java https://github.com/THM-MoTE/mope-server

plot in jupyter-lab

Example works in Jupyter notebook ("plot" displays results of simulation), but does not display anything for Jupyter Lab.

Help with installation in ubuntu 20.04

I can't install jupyter-openmodelica in ubuntu 20.04. The kernel does not appear in the list or in jupyter kernelspec list

• There is no kernel.json file, which I have used to install other jupyter kernels.
• You mention that I should set the OPENMODELICAHOME variable, but I don't know what value should it take after an openmodelica installation from the official repositories.

Regards

Syntax Highlighting doesn't work.

The mime type required for codemirror to highlight modelica code is text/x-modelica. The current specified type text/modelica does not get highlighted.

Runtime Interrupted errors.

Kernel can not be started because of "ImportError: No module named omniORB"

I just did a fresh install under Python 2.7 and the kernel can not be started because of a missing module. This is on a Ubuntu 16.04 64bit. So some dependencies must still be missing. OMPython itself runs fine.

from omniORB import CORBA
ImportError: No module named omniORB

docker link dead

hi there,
the link to docker is now dead... is this method still supported?
cheers

Numpy dependency not recorded

This is a really bite-sized issue. The dependency on numpy is not reflected in setup.py's install_requires.

At the same time a dependency on OMPython should be added. Here, a minimum OMPython could maybe be set such that the requirement of OpenModelica >1.12.0 (see #5) could be codified in that way (since OMPython comes with Openmodelica, right?)

Bump version number because of ZMQ

Since this is now implemented a version bump might be in order. Also please use semver. So 1.1.0 should be fine.

New ZMQ version kernel does not start

I'm getting the following error message:

File "/opt/conda/lib/python3.6/site-packages/openmodelica_kernel/kernel.py", line 39, in <module>
reload(sys)
NameError: name 'reload' is not defined

Plot is not displayed in line

I successfully installed jupyter-notebook and the openmodelica kernel on mac (using Python2.7).
Simulation works and even plotting (with plot(x); a window with OMPlot opens, with plot(x) (without semicolon) the plot was shown in line.
However, since I installed anew (tried if Python3 works, but did not, so I reinstalled everything for 2.7) plotting no longer works in line ("No result File Generated"), external plot(x); works fine.
Anyone got an idea what is going on?
