openfoam / openfoam-6 Goto Github PK

hey Openfoam! I'm not sure where your bug tracker is, but this is a tiny issue with the documentation here that I hope helps someone in the future! We were working on building a Docker container details here using an Ubuntu 16.04 base and a lot of issues came down to missing wget (so the ThirdParty libraries weren't built) and then ld issued a bunch of missing library commands. So - if we just add it to the list, many future users will likely appreciate :)

I can't find the basicMixture.C file in OpenFOAM-6/src/thermophysicalModels/basic/mixtures/basicMixture/ path.

Upgraded to OpenFOAM 6, compiling on ppc64le on Debian Buster with GCC 7. Every tool aborts with a "Floating point exception" regardless of whether MPI is used or not. OpenFOAM 5 did not have this problem.

To remove the 1 cell thickness of 2D openfoam meshes to get a true 2D surface mesh for Fluent .msh format

Hi All,
I‘m doing a 2D axis symmetry case which is need to use wedge mesh. The circumferential velocity(z direction) which I don't care about is calculated and it is hard to be convergent. Therefore, I wanna set different "residualControl" on velocity field "U", for example,

    residualControl
    {
        p               1e-3;
        //U               1e-5;
        Ux              1e-5;
        Uy              1e-5;
        Uz              1e-2;
        "(k|epsilon)"   1e-3;
    }

However, I found there was no the capability of component "residualControl", it seemed like that there is no "residualControl" set on "U" when I changed the "U" to the "Ux, Uy, Uz", though it didn't show any error or warning when I did this change.
Any reply will be great appreciated! Thanks!

currently foamCloneCase script is not accepting target directory name on ubuntu terminal with double tab.
e.g. foamCloneCase cavity .
If it does foamCloneCase cavity {to automatically select "cavity" word }2.

I read this https://openfoam.org/download/source/ explanation on how to compile OpenFoam from source. I tried running this script:

#!/bin/bash
apt-get install build-essential flex bison git-core cmake zlib1g-dev libboost-system-dev libboost-thread-dev libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev
apt-get install qt4-dev-tools libqt4-dev libqt4-opengl-dev freeglut3-dev libqtwebkit-dev curl

rm -r OpenFOAM-6

cp -r OpenFOAM-6 /opt/

export WM_COMPILE_OPTION=Debug
/opt/ThirdParty-6/Allwmake -j
/opt/ThirdParty-6/makeParaView
wmRefresh
/opt/OpenFOAM-6/src/Allwmake -j

But this script failed with the following output:

... a lot of output without erros ...

I would be thankful if anyone could explain to me why the compilation failes and how to fix it.

Additional Info:
OS: Linux (Ubuntu 18.04)

I was having persistent errors with running OpenFoam-6 (just downloaded) and having MPI_BUFFER_SIZE undefined. This is on an openmpi-4.0.1 + ubuntu 18.04 system and I'm 100% sure that the same OpenMPI was used to compile and run.

This happened when launched with mpirun or srun.

This did not help:
export MPI_BUFFER_SIZE=2000000

Nor did telling mpirun to pass in the variable with -x.

I recommend on line 123 of UPstream.c you call getenv, not getEnv.

Also if it's undefined I'd either set a default, or just skip the call to MPI_Buffer_attach.

With the above mentioned change it seems to work well.

Hello,
I am tired of searching the internet to get an answer to my question, so I decided to ask it here!
In Ubuntu:
Without installing OpenFOAM-dev. How can I get OpenFOAM with the latest bug fixes? do I have to wait till OpenFOAM 7 to be released?
or do you provide regularly pre-compiled versions via ubuntu repositories? if yes when?
Please answer me.

Why does the makeThermoParcelForces macro create only SphereDragForce and NonSphereDragForce, while makeParcelForces creates also WenYuDragForce, ErgunWenYuDragForce, and PlessisMasliyahDragForce?
