🔨 Investigate compiling openfoam

[oguzhankoral]

Compiling lightweight openfoam9 will decrease the size of the layer.

Currently we use it as below but it allocates 1.09 GB

RUN apt-get -y --no-install-recommends install openfoam9

But the source files are around 150 MB, so we can download source files to image and compile ourselves with lightweight version by eliminating unnessary builts.

# Download and compile OpenFOAM 9 manually
WORKDIR /opt
RUN wget -O OpenFOAM-9.tar.gz http://dl.openfoam.org/source/9
RUN mkdir OpenFOAM-9
RUN tar -xzf OpenFOAM-9.tar.gz -C /opt/OpenFOAM-9 --strip-components=1

RUN echo "source /opt/openfoam9/etc/bashrc" >> /root/.bashrc

# Compiling script (tooks more than 1 hour with failed compiling, there is no enough error report why it happenned..)
WORKDIR /opt/OpenFOAM-9
RUN Allwmake

# Cleanup unnecessary files to reduce the image size
RUN rm -rf /opt/OpenFOAM-9.tar.g

The second option requires more know how to compile it properly and feasibilty analysis to understand is it really make sense or not.
