I was trying to install OpenFoam exactly as mentioned on their website. But when I run simpleFoam -help it says command not found, even after restarting my PC. I am using Ubuntu 20.04 lts.

When I run tail ~/.bashrc, this is the output

        . "/home/hell/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/home/hell/anaconda3/bin:$PATH" fi fi unset __conda_setup # <<< conda initialize <<< source /opt/openfoam9/etc/bashrc  Here are the contents of the directory /opt/openfoam9/etc (base) hell@Dell-Precision-T1600:/opt/openfoam9/etc$ ls
bashrc     cellModels     config.csh  controlDict  paraFoam    templates
caseDicts  codeTemplates  config.sh   cshrc        README.org  thermoData


But there is something which I don't understand. When I run source /opt/openfoam9/etc/bashrc in the terminal, this is what I get /home/hell/anaconda3/bin/mpicc: line 285: x86_64-conda_cos6-linux-gnu-cc: command not found. But this has nothing to do with OpenFoam.
