Thanks a lot!

I tried with version 1712 - and it works. Very nice tool!

FieldValueExpressionParser
 

Hi,


I have an installed version of OpenFoam-2.3.0 on supercomputer. I have the following error while tried to install swak4Foam





The log file is attached. Thanks in advance for any help.


Regards,


Elham

I think the problem is that around the time of 2.3 the behaviour of "a & b" with a and b being symmetrical tensors changed. Your OpenFOAM-version says that the result is a general tensor while swak4Foam assumes that it will be a symmetrical tensors. The quickest solution would be to remove the offending rule from the grammar and hope that you never need it. Go to FieldValueExpressionParser.yy and line 3162 in that. The rule starts with a line starting with a pipe symbol ("|"). Remove the rule that the line is in (just all the lines until the next rule). In my experience 93.5% of all applications of swak4Foam don't involve tensor arithmetics so you might be fine

Dear Bernhard,


I have deleted the rule and try to compil;e but still have the same error. I have attached the FieldValueExpressionParser.yy file. I am wondering if I should remove some more rules since the other rules around are similar to the one that I removed.



Thanks for your attention.


Elham

No. The other rules should be fine.


Before trying anything else do ./Allwclean and recompile. Maybe the intermediate file from the grammar was not correctly produced/written


Anyway: check the log if it is really exactly the same error


BTW: the current develop-branch in the repository compiles with 2.3. But it uses the necessary workarounds

Just checked my sources. The workaround is needed in 2 other places. So maybe ypur error message was similar but not the same (because it stumbled on those cases). Check the line in the error messages (look for the string "error:". Near that is the actual places it happened)

I am trying to install swak4foam in openFOAMv7. Getting above error, can anyone help me?


Thanks in Advance

Which version of the sources is this? Currently only the development version supports OF7

Hello divyesh, maybe you can try like the way I explained here? It worked for me.

OpenFOAM v1912 Ubuntu 20.04
 

Hi,
i am facing trouble in compiling swak4Foam for OpenFOAM v1912. I have tried the default, develop and p1912 branches in the mercurial repository with no success. One of the error messays state that:

which is quite strange since OpenFOAM v1912 is the latest version. Also, these are the remaining error messages:


And, the compilation stops at:

This is the complete build log. Any guidance to resolve this issue is very much appreciated. Thank you.

Installation Errors of develop version on of7
 

Dear Sir/Madam,


This is Yuke. I've installed OpenFOAM 7 on my computer (Ubuntu 20.04.1 LTS). When I was installing swak4FOAM, an error keeps coming after wclean several times. I haven't found any solutions from the Internet. Please help me fix this.



I followed the installation instruction, as
in Folder: ~/OpenFOAM/yuke-7/

1) hg clone http://hg.code.sf.net/p/openfoam-extend/swak4Foam swak4Foam
2) cd swak4Foam && hg update develop
3) ./Allwmake > log.make 2>&1
4) ./Allwmake > log.make 2>&1
The attached is what was written in log.make profile.

If you want to use swakCoded-function object or compile software based on swak set the environment variable SWAK4FOAM_SRC to /home/yuke/OpenFOAM/yuke-7/swak4Foam/Libraries (most people will be fine without setting that variable)

Thanks in advance.
Best, Yuke

I think the only problem is that funkySetAreaField should not compile on your machine: it needs the finiteArea-stuff which only foam-extend and the ESI release have.


So there is a problem in the compilation script that I have to fix (so that it doesn't try to compile the utility on OpenFOAM from CFD-direct)


If there are no other problems then you should be fine

Hi,
Just wanted to remind that I am still facing this issue. I also tried compiling swak4FOAM for other versions of OpenFOAM - v1906, v2006, but the same issue persists. My operating system is ubuntu 20.04. swak4FOAM was running fine with OpenFOAM v1906 when I was using ubuntu 18.04 on my PC. Also, I didnt face any issues when I installed swak4FOAM and OpenFOAM v1906 last year on my university's cluster which has CentOS. Do I need to take extra precautions when I am compiling swak4FOAM on ubuntu 20.04? Or are there some other issues with my setup?
Best wishes,
Kiran Sripathy.

Install swak4Foam in OpenFOAM-v2012
 

log.make:
Some scripts require a binary 'python' to be installed
It doesn't matter if this is Python 2 or 3
This problem is caused by Linux distros that install 'python2' and/or 'python3' but no python
On such distros usually a packages exists that links 'python' to one of those


It's the latest version: OpenFOAM-v2012, and I install the swak4Foam development version, getting above error, can anyone help me?

Thanks in Advance

The problem is not swak4Foam. The problem is your distro: usually Linux-distros have an executable "python" that points to either "python2" or "python3". The scripts in swak are written in such a way that they work with both of them.
Ubuntu has decided in its newest version that there is no "python". Only "python2" and/or "python3"
To fix that it has to be made sure that "python" points to one of the two. The ways to do that is

1. install a package that does that (I hear Ubuntu 20.04 has such a package
2. set a symbolic link in a directory in PATH that points to either python2 or 3

It depends on your Linux-distro and whether you have admin rights which is the past way

Could you solve it?

You are trying to write in /usr/lib/openfoam which is not writable without root.


Try this

mkdir -p $FOAM_RUN


then execute Allwmake script

you can run code in Ubuntu-20.04LTS:
