cfMesh Installation with OpenFOAM 6?
 

I am currently trying to install cfMesh unto my linux computer as i know cfMesh is really useful. I downloaded v1.1.1 but when i tried to source the bashrc file in the cfMesh directory there was an error, as it tried to reference to OpenFoam2.3.0 while i have openfoam6 currently installed (bashrc referenced to /opt/OpenFOAM-2.3.0 while what there is /opt/openfoam6). So i uninstalled it and went to install the newer version cfMesh-v.1.1.2. Although there is no installer but rather only a zipped file containing the tutorials/commands etc.
So i was wondering if anyone can help me compile the cfMesh code into openfoam6.
Any help is appreciated, Thank you
Ps. I am still relatively new at using linux as well as openfoam.
I have currently solved the problem. There was an error sourcing the correct libraries.

Hi


There is dibian version , not need for compiling and setting envir.

cfmesh is included in OPENFOAM 1806.

Installation error with OpenFOAM 6
 

hi there!


I'm trying to install cfMesh on ubuntu 18.04 and openFOAM 6.0, however I persistently get an error in the process. My knowledge on linex in general is not good enough to know how to begin to troubleshoot, so I would greatly appreciate some advice.
Below is some of my log file from trying the install

EDIT: Managed to install V1.1

Hi,



did you solve the error? I am also getting the same error. Please let me know the procedure. Thank you.

I did, by changing many of the source files to work with newer versions of openFoam. Unfortunately, this was months ago and I cannot remember what or how I changed them

cfMesh installation in OpenFOAM 6
 

Dear all,


I would like to get cfMesh running in combination with OF6. I searched for this special issue, but I couldn't find any solution. I tried to build it from source (v1.1.2), but when compiling there are two/three errors:


1) In OF6 the folder edgeMesh in the src-directory doesn't exist anymore, it seems, that the respective files are now in the meshTools/lnInclude-folder. I tried to chnage that in the Make files of cfMesh, so the error message disappeared, but I don't know if this helped or was even necessary, since there are additional errors.


2 + 3) The actual compiler errors seem to have their origin in the polyMeshGen.H and polyMeshGen.C-file. It says that 'metaDict_' and 'IODictionary' were not declared in this scope and that the constructor does not not have these field names.


Does anyone know if and how this can be fixed or if it is even possible to use cfMesh with OF6 or if I try to do something impossible?


Thanks,
stockzahn

Greetings to all!

Merry Christmas! I am re-gifting cfMesh for OpenFOAM 5 and 6 to everyone this year ;)

This to say that I've revised/revamped the wiki page for cfMesh at openfoamwiki.net: https://openfoamwiki.net/index.php/E...ilities/cfMesh

And that there you will now find instructions regarding:

1. Where you can find cfMesh, its source code and in which OpenFOAM/foam-extend versions is already present and how to build it from source code if not present by default.
   • So much so that there are actually two sets of instructions on how to install cfMesh with OpenFOAM 5 and 6! :)
2. Where you you can find the tutorials.
3. Where you can find the User Guide.

Best regards,
Bruno

Hi All,


Happy new year!


I have similar aforementioned compilation problems both with the original version using of4x, as well as the links provided by Bruno for of5x and of6x.


Solutions will be appreciated.

Quick answer: I need concrete information about what exact error messages you are getting.

Hi Bruno,

Please find attached make log files for the compilation of cfMesh in both 4x and 5x.

I tried to follow both the steps in 2.1.1 and 2.1.2 provided here (https://openfoamwiki.net/index.php/E...ilities/cfMesh), but both gives me a similar error message.

Please let me know if you need more info.

Regards
Robert

Quick answer @Robert: OK, now I can see the problems... so there are two possible origins of problems here:

1. GCC 7 is being used, which is one possible origin of this problem.
2. Another one is that 64-bit labels ("WM_LABEL_SIZE=64" is defined) are being used in your builds of OpenFOAM 4.x and 5.x.

So my question to you is this: Are you really planning on running OpenFOAM with meshes that have more than 2147483648 cells/faces/vertices?
It's something around 100 to 200 million cells, which requires from 100 to 300GB of RAM, depending on the mesh complexity...



The reason for this question is because:

1. You should be able to compile cfMesh without problems with OpenFOAM 4.x and 5.x if compiled with 32-bit labels.
2. Which means that you would be able to use cfMesh right away if this were the case.

In the meantime, I'll try to look into this in more detail. With luck, this is already solved on OpenFOAM.com and I can backport the fixes from there...

Thanks, Bruno, for taking a look at it.



I may need to run 100 million cells case at some point, but not regularly.


Do I need to recompile FOAM with 32 bit and certain gcc version? Please let me know if you find the fixes.

It looks like wyldckat's instructions work for compiling cfMesh against OpenFOAM 7 as well :-)

Ol´a Bruno,


I'm having trouble installing cfMesh with OpenFOAM 6 if compiled with 64-bit labels.

I have pasted in the contents of the log.Allwmake file.

Any help would be greatly appreciated.



Thank you,
Manuel

Hi Manuel

I had exactly the same issue while installing and I followed the instructions provided by Bruno in comment 8 of this thread. That has sufficient information.

Krao

yeap I also followed his instructions, but unfortunately no luck during compilation, it fails :(
I assume the prbl is the 64-bit labels ("WM_LABEL_SIZE=64" is defined) since I used this option for building OF6, see post#12

Can you share your edited files as described in post 8, maybe something missing there and people here may help you to fix it.

Krao

hmm, I have followed the official repository steps , only made changes to the meshLibrary options file .. is there something I missed???



this is my 'meshLibrary/Make/options' file:



--snip
--snap

Try this I have just compiled on OpenFOAM 7

I followed the instructions in post 8 once again and installed cfMesh on my 64bit machine. There was no problem. I think they have made some changes to the make file already, as you can see in my post. Try it once, good luck.
