I thought I did it, I deleted the openFoam's folders I've created before, and the old images... Maybe it's not enough.

Is there a command to clear evertihing in order to restart from the beginning?

Could my difficulties related to the M1 processor which is Arm and not x86?

The emulation mode indeed is pretty slow since the dockerhub images are x86_64 Ubuntu. Supporting Arm64 Ubuntu is a bit of a problem (painfully slow package builds), but you can easily create your own local docker image fairly quickly.

We supply all of the docker files and resource files here:
https://develop.openfoam.com/packaging/containers

You will want to create an image using the openSUSE packages. This is described in the corresponding file
https://develop.openfoam.com/packagi...eap-Dockerfile

After running docker build on this, you can either tag it with the "opencfd/.." prefix so that the openfoam-docker script finds it, or run the openfoam-docker with -image=<your-image>

Thank you Olsen, i did what you suggested... it works much better! Thanks

Hello All

The reason for this error is that "feexceptErsatz.H" refers to the x86_64 structure of fenv.h.　"feexceptErsatz.H" needs to be rewritten so that it uses the arm64 structure.

Here is how I built it, for your reference.

Hi Federico, yes I did...

But, is your Mac equipped with an M1 SoC or with a x86 cpu?

In another post, a forum member suggested this:

"You'll need to remove the sigfpe part(seems like Apple silicon doesn't support this feature?) then it should compile.
https://github.com/mrklein/openfoam-...ment-850090915 "

But I don't know exactly what this means...

Nice! I have added a corresponding issue for updating the upstream.

Following the wonderful advice of LongGe and Federico, I managed to install OpenFoam-v2106 on Mac M1!

In a final step, I need to define LD_LIBRARY_PATH to set the path to the third party libraries. How do I do so?

Thx!

[dlahaye]

Update:

Various of the third party packages fail compile with Clang version 12.0 on Darwin. I failed to see this earlier. (Switch to gcc on Darwin is not supported).

E.g. scotch fails to compile due to the gettimneoftheday function being implicitly declared in src/libskotch/conmon.c. I was not yet able to turn this error of using -Wno-error=implicit-function-declaration.

Kahip fails due to the compiler not finding misc/omp.h . I was not yet able to extern the include directory with this path.

Metis does compile after manual download and installation of cmake using brew.

I am currently trying to run decomposePar using Metis. After installation LD_LIBRARY_PATH remains empty. Setting LD_LIBRARY_PATH manually does not cure the issue.

[LongGe]

Hello All

In my case, I installed the third party with brew. As described here.

https://github.com/mrklein/openfoam-...ster/README.md

[dlahaye]

Further updates:

(1/3): good news: I managed to install Cmake using brew, to download Metis from the repository, to install Metis, to set DYLD_LIBRARY_PATH (observe MAC-OS convention) manually and to run decomposePar to obtain a decomposition. So far, so good.

(2/3): first question: A parallel run of simpleFoam fails, that is, "mpirun -np 4 simpleFoam -parallel" returns with "The dummy Pstream library cannot be used in parallel mode". The same issue however was however reported e.g. here https://develop.openfoam.com/Develop.../-/issues/1970. Will need to give it a look.

(3/3): second question: the compilation of the third party mesher cfMesh using Clang fails. I will give specifics in a next update.
