Installing OpenFOAM with MPICH

Hello!

I am trying to install with mpich3.2 in CentOS7. I made couple of changes in the root folder.

In etc/bashrc, I have changed the following

Code:

export WM_MPLIB=MPICH

In etc/config.sh/mpi, I have changed the following

Code:

MPICH)

    export FOAM_MPI=mpich-3.2

    export MPI_ARCH_PATH=/home/D/mpich-3.2/install

    export MPI_HOME=$MPI_ARCH_PATH

    export FOAM_MPI_LIBBIN=$FOAM_LIBBIN/mpich-3.2



    # Could be sourced from ThirdParty with incomplete environment

    if command -v _foamAddLibAuto > /dev/null 2>&1  # Normal sourcing

    then

        _foamAddPath    $MPI_ARCH_PATH/bin

        _foamAddMan     $MPI_ARCH_PATH/share/man

        _foamAddLib $MPI_ARCH_PATH/lib

    fi

    ;;

But while compiling the code I get the following error in both V1812 and V1906

Code:

/home/D/foam/OpenFOAM-v1812/src/OpenFOAM/lnInclude/IOobject.H:497:14: note: because ‘Foam::IOobject’ has user-provided ‘void Foam::IOobject::operator=(const Foam::IOobject&)’

I would like to know if I need to change anything else apart from these values.

Thanks for your time.

Hmmm.. let's issue a ticket in the issue tracker in GitLab.

Any further information you can provide regarding your compilation?

Thanks for the reply!

Let me know the information will be required and helpful to identify the error?

I have used GCC 9 and MPICH 3.2 for compilation.

I assume you've downloaded the mp* package into the ThirdParty dir?

I have run into the same problem but I have figured it out on Ubuntu 18.04. But I bet it will work on Centos 8 as well. Here is what I propose, you may want to install Openmpi alongside with the MPICH compiled from source. And once you got a way to switch back and forth, Problem solved! I suggest using "bash", which is a way to edit your ~/.bashrc or ~/.profile.

Add following lines to .bashrc

## switch between mpich and openmpi
use_mpi () {
shopt -s nocaematch
case "$1" in
mpich) export PATH=/home/to/your/MPICH/bin:$PATH
openmpi) export PATH=/usr/bin:$PATH ;;
*) return 1 ;;
esac
shopt -u nocasematch
}

After adding those lines, type
1. "source ~/.bashrc" to activate the commands;
2. "use_mpi mpich" will allow you to use mpich in the current terminal;
3. "use_mpi openmpi" will allow you to use openmpi.

Then you can handle different versions of MPI on your system (not limited to two, could be three, four, ..., etc) . I feel this is more elegant other than messing with OpenFoam source code before you are an advanced user.

Hope this will help you.

No! I built the package directly as I needed the newer version.

I was able to install OpenFOAM with IntelMPI.

Thanks for your concern!

Thanks for your help! Will try and get back to you.
