[Postrus]

Hi everyone,

I recently discovered Openfoam and find it a really interesting tool by itself and with all the other codes using it so I tried to install it on a clean new Virtualbox VM on Ubuntu x64 (I use .bashrc) to experiment some code based on OpenFOAM.

I followed the different steps for OpenFOAM installation on my Ubuntu machine HERE (yes I wrote every steps carefully as there is always problems when I first try to install an open source program) :

apt install gcc
gcc –version
sudo apt-get install build-essential flex bison git-core cmake zlib1g-dev libboost-system-dev libboost-thread-dev libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev
sudo apt-get install libqt5x11extras5-dev libxt-dev qt5-default qttools5-dev curl
mkdir $HOME/OpenFOAM
cd $HOME/OpenFOAM
git clone http://git clone https://github.com/...OpenFOAM-7.git
git clone https://github.com/OpenFOAM/ThirdParty-dev.git
source $HOME/OpenFOAM/OpenFOAM-7/etc/bashrc
source $HOME/.bashrc
cd $HOME/OpenFOAM/ThirdParty-dev
./Allwmake
./makeParaView
wmRefresh
cd $HOME/OpenFOAM/OpenFOAM-7
./Allwmake -j

I need OpenFOAM 7 instead of the dev version for the codes I want to try so I installed this version. But when I run this last command line, I have an error with Scotch which is one of OpenFOAM dependancy for parallel runs (cf. first attachment) :



I tried multiple times to change the OpenFOAM version, uninstalled and installed Scotch, but nothing works and I always still have the same error.

I found on this forum the following post which seem close "HERE", but I tried the answers and it didn't worked.

It seems like the installing procedure know that scotch is in the ThirdParty-7 folder but still try to find a part on my OpenFOAM-7 folder so I don't really understand how I can solve this problem as the "scotchDecomp" element doesn't seem to be in any of my folders.

My file tree is as follows in $HOME/OpenFOAM (cf. second attachment) :


Did anyone encountered this problem or may know how to solve it ? I am really new on Ubuntu and OpenFOAM as I am just getting started and I would really need some help if someone would be so kind

Thank you and have a nice weekend.

Probably the same as this question: OpenFOAM 6 installation: ptscotch.h file not found


Same answer (I think) - probably easiest is to simply use the precompiled binaries for ubuntu:
