Newbie Problems

[wallbob]

I have a Mac mini with Apple Silicon and I'm trying to build a native instance of OpenFOAM v9. I followed the directions located here:

https://github.com/mrklein/openfoam-os-x/wiki/OpenFOAM(R)-release-&-Homebrew

Everything works fine until I get to the following command:

git apply OpenFOAM-9.patch

I receive the following error:

error: patch failed: etc/bashrc:154 error: etc/bashrc: patch does not apply

Any suggestions?

[mrklein]

I would suggest to use more recent OpenFOAM-9 source code. Either checkout sources from git repository, or use patch release, as described here: https://openfoam.org/news/v9-patch/.

The problem is that between release 9 and time when patch was created, there was source code change:

# Evaluate command-line parameters and record settings for later
# these can be used to set/unset values, or specify alternative pref files
export FOAM_SETTINGS="$@"
_foamEval $@

was changed to

# Evaluate command-line parameters of the form "param=keyword" or unset
# parameters with "param="
export FOAM_SETTINGS="$@"
_foamParams $@

And this breaks application of the patch.

So, I tried the following:

1) download the latest dev version of the source code:

curl -L http://dl.openfoam.org/source/9 > OpenFOAM-9.20211007.tgz

2) download the latest version of the patch

curl -L https://raw.githubusercontent.com/mrklein/openfoam-os-x/master/OpenFOAM-9-2b1d7d67c.patch > OpenFOAM-9.patch

However, when I run the command "git apply OpenFOAM-9.patch" I get the same error:

error: patch failed: etc/bashrc:154 error: etc/bashrc: patch does not apply

[mrklein]

Correct URL for patch release is http://dl.openfoam.org/source/9.20211007. So, you do:

$ curl -L http://dl.openfoam.org/source/9.20211007 | tar xz
$ mv OpenFOAM-9-20211007 OpenFOAM-9
$ cd OpenFOAM-9
$ curl -LO https://raw.githubusercontent.com/mrklein/openfoam-os-x/master/OpenFOAM-9-2b1d7d67c.patch
$ git apply OpenFOAM-9-2b1d7d67c.patch

With your command

curl -L http://dl.openfoam.org/source/9 > OpenFOAM-9.20211007.tgz

you just downloaded release 9 Into a file with the name OpenFOAM-9.20211007.tgz. And as a result, you got the same error.

Thanks for the help. Now it is compiling!

Next error:

When I run Allwmake it goes for a long time then stops when trying to compile scotch. Here is the error:

using SCOTCH_ARCH_PATH=/usr/local

This one is caused by new Homebrew package installation location on M1. On x86_64 Homebrew links formulae in /usr/local/opt, on M1 it is different. So, you open etc/config.sh/mac/scotch (and then etc/config.sh/mac/metis) and put there location of Scotch and METIS (SCOTCH_ARCH_PATH and METIS_ARCH_PATH). Guess, in future patch versions search logic should be adapted to use brew --cellar.

Hello,

Thanks for posting the problems, I faced similar issues (M1Pro 10 core, 32GB RAM) and this helped. But when I tried to test the installation, it returned such errors:

$ mkdir -p "$FOAM_RUN"
$ run
$ cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity .
$ cd cavity
$ foamRunTutorials
dyld[50136]: symbol not found in flat namespace '_MPI_Abort'
Running blockMesh on /Users/massisenergy/OpenFOAM/massisenergy-9/run/cavity
/Volumes/OpenFOAM/OpenFOAM-9/bin/tools/RunFunctions: line 56: 50140 Abort trap: 6           $APP_RUN "$@" > log.$LOG_SUFFIX 2>&1
Running  on /Users/massisenergy/OpenFOAM/massisenergy-9/run/cavity

log.Allwmake_backUp.txt

From the log, I could not see any obvious error that can be related to dyld ..., what is the issue here?

[mrklein]

Last time similar problem was reported, the was a problem of mixing Rosetta and native code. This also can be a problem of SIP. Did you try to run foamRunTutorials commands from command line? Since, there is no Allrun script in cavity tutorial, foamRunTutorials command runs these two: blockMesh and icoFoam. Could you run them from command line?

[massisenergy]

Thanks for your response.

I am not sure what do you mean by 'commands from command line'. Any OpenFOAM commands must be run from command line AFAIK. I attach screenshots from my terminal (iTerm2), if that helps.

How do I go about 'mixing Rosetta and native code'?

I'll disable SIP and then try again.

[mrklein]

foamRunTutorials is a script, which is quite simple: either it runs Allrun script in the current folder, or it creates mesh with blockMesh and runs solver (which is extracted from controlDict).

If there is a problem with SIP, usually it manifests when a case is run from script (like foamRunTutorials) due to cleaned DYLD_LIBRARY_PATH. If you simply enter commands one by one (i.e. blockMesh, icoFoam) usually everything works.

Concerning Rosetta (https://en.wikipedia.org/wiki/Rosetta_(software)) I was referencing this thread: https://github.com/mrklein/openfoam-os-x/issues/62#issuecomment-850381759. Since I do not use M1, I do not encounter these problems, so I can not help you any further.

[massisenergy]

I ran blockMesh and icoFoam individually. The result is same. I'll try to understand and adopt according to the issue you've mentioned, thanks.

Also I should mention that in stead of mounting using hdutil, I have used ln -s /Volumes/OpenFOAM $HOME/OpenFOAM, can that be causing those issues?
