Hello,
I have successfully compiled of-v1812 on macOS v10.15.2 using this guide https://github.com/mrklein/openfoam-...ase-&-Homebrew provided by Alexey Matveichev.
preprocessing tools work fine and case runs in serial.
But when I try to run it in parallel using bash script
Code:
#!/bin/sh
cd ${0%/*} || exit 1                        # Run from this directory
. $WM_PROJECT_DIR/bin/tools/RunFunctions    # Tutorial run functions
#restore0Dir
runApplication blockMesh
runApplication decomposePar
runApplication setFields
#foamJob -parallel multinInterFoam
mpirun -np 6 multiInterFoam -parallel > log.multiInterFoam
#------------------------------------------------------------------------------
i get error:
Code:
--> FOAM FATAL ERROR:
The dummy Pstream library cannot be used in parallel mode


    From function static bool Foam::UPstream::init(int &, char **&, const bool)
    in file UPstream.C at line 46.

FOAM exiting
Interesting that if i run command
Code:
mpirun -np 6 multiInterFoam -parallel > log.multiInterFoam
after preproccesing case everything works fine.


I did read previous threads (Pstream library error in parallel mode and others) about this issue but nothing helped so far.
I have openmpi installed on my system using brew.


Command results:
1. echo $FOAM_MPI
openmpi-system
2. echo $MPI_ARCH_PATH
/usr/local/Cellar/open-mpi/4.0.2
3. /usr/local/bin/mpirun


My ~/.zshrc file end:
Code:
#source /Users/xxx/OpenFOAM/OpenFOAM-v1812/etc/bashrc WM_NCOMPPROCS=6 WM_MPLIB=SYSTEMOPENMPI
source /Users/xxx/OpenFOAM/OpenFOAM-v1812/etc/bashrc
alias paraFoam="touch case.foam && /Applications/paraview.app/Contents/MacOS/paraview --data=case.foam"
alias solvers='cd ~/OpenFOAM/xxx-v1812/applications/solvers/'
My $FOAM_ETC/bashrc file:
Code:
 66 # [WM_COMPILER_TYPE] - Compiler location:
 67 # = system | ThirdParty
 68 export WM_COMPILER_TYPE=system
 69
 70 # [WM_COMPILER] - Compiler:

 72 #   Clang | Clang3[7-9] | Clang[4-6]0 | Icc | IccKNL | Cray | Arm
 73 export WM_COMPILER=Gcc
 74
 75 # [WM_ARCH_OPTION] - Memory addressing:
 76 # = 32 | 64
 77 #   * on a 64-bit OS this can be 32 or 64
 78 #   * on a 32-bit OS, it is always 32-bit and this option is ignored
 79 export WM_ARCH_OPTION=64
 80
 81 # [WM_PRECISION_OPTION] - Floating-point precision:
 82 # = DP | SP
 83 export WM_PRECISION_OPTION=DP
 84
 85 # [WM_LABEL_SIZE] - Label size in bits:
 86 # = 32 | 64
 87 export WM_LABEL_SIZE=32
 88
 89 # [WM_COMPILE_OPTION] - Optimised, debug, profiling:
 90 # = Opt | Debug | Prof
 91 export WM_COMPILE_OPTION=Opt
 92
 93 # [WM_MPLIB] - MPI implementation:
 94 # = SYSTEMOPENMPI | OPENMPI | SYSTEMMPI | MPI | MPICH | MPICH-GM |
 95 #   HPMPI | CRAY-MPICH | FJMPI | QSMPI | SGIMPI | INTELMPI | USERMPI
Code:
  96 export WM_MPLIB=SYSTEMOPENMPI
I am puzzled by the source of this problem and would be grateful if someone can help me.
Best regards,
Tonnykz
