DWSIM - Open Source Process Simulator / Discussion / Linux Platform (New UI): Running DWSIM in Docker

Hello,
I'm trying to build a Linux Docker container so as to be able to automate runs for parametric analysis, e.g., figure out how certain simulation outputs change based on changes on inputs. I don't want to run the UI - I just want to run it in headless mode.

Below is the Dockerfile I used to create the Docker image. It has...
Ubuntu 20.04 as a base
Python version: 3.8.10
Mono version: 6.12.0.122
DWSIM version: 7.1.2
pythonnet version: 2.5.2

FROM ubuntu:20.04

RUN apt update
RUN apt upgrade -y

# Set timezone variables for tzdata
ENV TZ=Asia/Kolkata
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# Install python, pip, vi and wget
RUN apt install -y vim python3 python3-pip wget

# Install mono based on https://www.mono-project.com/download/stable/#download-lin
RUN apt install -y gnupg ca-certificates
RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
RUN echo "deb https://download.mono-project.com/repo/ubuntu stable-focal main" | tee /etc/apt/sources.list.d/mono-official-stable.list
RUN apt update
RUN apt install -y mono-complete

# Install pythonnet
RUN pip install pythonnet

# Download and install DWSIM
RUN wget https://downloads.sourceforge.net/project/dwsim/DWSIM/DWSIM%207.1/7.1.2/dwsim_7.1.2-amd64.deb
RUN apt install -y ./dwsim_7.1.2-amd64.deb

Within the running container, I use this python file to try and create a flowsheet. It is based on the sample code in section 34.5.5 of the user guide - but it does not have the pythoncom import because I can't install pywin32 on linux.

import clr

dwsimpath='/usr/local/lib/dwsim/'

from System import String, Environment
from System.IO import Directory, Path, File

clr.AddReference(dwsimpath+'DWSIM.Automation.dll')
clr.AddReference(dwsimpath+'DWSIM.Interfaces.dll')

clr.AddReference(dwsimpath+'DWSIM.Thermodynamics.dll')
clr.AddReference(dwsimpath+'DWSIM.UnitOperations.dll')
clr.AddReference(dwsimpath+'DWSIM.Inspector.dll')
clr.AddReference(dwsimpath+'DWSIM.MathOps.dll')
clr.AddReference(dwsimpath+'TcpComm.dll')
clr.AddReference(dwsimpath+'Microsoft.ServiceBus.dll')

from DWSIM.Automation import Automation2
from DWSIM.Interfaces.Enums.GraphicObjects import ObjectType
from DWSIM.GlobalSettings import Settings

Directory.SetCurrentDirectory(dwsimpath)

interf = Automation2()
sim = interf.CreateFlowsheet()

When I try and run this file though, it crashes when the Automation2 object is being initialised:

Initializing DWSIM Automation Interface...

I've tried to run a couple of troubleshooting tests as specified on a couple of the other topics but I'm not familiar with mono or C# so I don't know if I'm doing them right. I'm not sure if I'm missing a package or whether there's some sort of incompatibility between the software versions I'm using. Any thoughts on what's going wrong? Any help would be greatly appreciated.

Thanks!

I also tried the test file located here (with a minor modification for the path of the file to be loaded): https://github.com/DanWBR/DWSIM.Automation.Test.macOS/blob/master/DWSIM.Automation.Test.macOS/Program.cs
within the container. This did initialize the automation interface, but then gave a whole bunch of other errors:

Initializing DWSIM Automation Interface...
DWSIM Automation Interface initialized successfully.
Filepath: /usr/local/lib/dwsim/test.dwxmz
Initializing the Flowsheet, please wait...
