Somethings I found tonight when I was reading due to work keeping me up : )

How to represent Modelica style If-Equations using MTK

17

I suppose this issue may very well be a documentation issue. Version of MTK is the latest (As of this writing 8.6.0) and the version of Julia was 1.7.2 Related...

Hi, John here again sorry for a long post but I include everything for replication and (For context) (Title stolen from one of Yingbos comments) I have the following Modelica...

Long compilation time some numbers + included examples

Hi, I would like to start by apologizing for a long text... I have the following models, note these models are automatically generated based on different parameters to the following...

IDA-key error when saving positions

Hi! I have the following system (see below) describing a bouncing ball. However, when running this with ` julia> plot(BouncingBallRealsSimulate((0.0, 3.0)), vars=(2))` I get the the following error: ``` ┌...

Possible for ZMQ freezes when receiving data

A similar issue to https://github.com/OpenModelica/OMJulia.jl/issues/12 could occur here as @arun3688 pointed out. I leave this issue as an open issue here as well. Some kind of polling should be implemented...

ZMQ freezes when receiving data

Send and recv is currently handled by ``` function sendExpression(omc, expr) ZMQ.send(omc.socket, expr) message=ZMQ.recv(omc.socket) return Parser.parseOM(unsafe_string(message)) end ``` The issue here is that I have managed to freeze it a...

Model with quoted variables does not simulate in OMEdit

### Description I have a variant of the DoublePendulum model produced by OM.jl (The Julia variant of the compiler). The model is fully scalarized, similar to how base Modelica is...

While the frontend handles a large portion of the standard components of the MSL, some of these currently need to simulate due to the backend not handling algorithmic Modelica and...

Backend fails to reorder the derivatives when a state variable occurs more than twice among the equations

[FinsModel.zip](https://github.com/JKRT/OM.jl/files/8993549/FinsModel.zip) The following model has the following equations sharing the same state variable: ``` D(mH) ~ 2.0 - lambda_1 - 2.0mH, D(mH) ~ l*w - cH*p, D(k) ~ inv, -D(k)...
