OpenFOAM 1812 - Compilation

Before compiling OpenFOAM we need to make sure, that all the needed libraries are installed.

Prerequisites

On Ubuntu 20.10 some packages need to be installed prior to compilation. On Ubuntu 20.10 the below list should work. To install them go to the console and:

sudo apt install gcc
(might be missing depending on installation)
sudo apt install libopenmpi-dev

sudo apt install zlib1g-dev

sudo apt install flex

Then, make sure you have access to the MPI library (both commands should print version information):

mpicc --version

mpirun --version
