Re: [Yade-dev] Capillary scripts

2016-09-13 Thread Klaus Thoeni 
Hi Jerome,

great addition and thanks for sharing the scripts.

One question, why did you use Matlab/Octave and not python? Python scripts 
would "fit" better into the trunk ;-)

I terms of where to upload the scripts. I would suggest a folder in  
"examples" with an example, your scripts and instructions. I think some people 
already used this approach. But anyway, this is just a suggestion. 

Cheers
Klaus

Re: [Yade-dev] Capillary scripts

2016-09-13 Thread Jerome Duriez 
Hello,


After a couple of private emails with Bruno, I can confirm that these scripts 
work with GNU Octave as well (in addition to the less open-source friendly 
MATLAB )


We mentionned with Bruno the possibility uploading these .m scripts on the 
wiki, however I would greatly prefer they are in trunk, in order to enjoy the 
revision tracking tools.

As these scripts are not bound, from my point of view, to any non open-source 
tool, I think it should be fine. Any opinion ? (Bruno ? others ?)


Another question is what would be the best trunk subfolder for these files ? 
trunk/scripts ?

Hi there,


Attached are three .m scripts aimed at generating capillary files for use with 
Law2_ScGeom_CapillaryPhys_Capillarity. Obviously, the idea, discussed 
previously here and there on the mailing lists, is to make this part of YADE 
more "open-source". Also, there is two major differences with previous (L. 
Scholtes') work:


* these scripts may generate capillary files accommodating any contact angle 
value, instead of 0 previously


* they provide new output as an "orientation tensor" defined from the 
fluid-fluid interface of capillary bridges. These data would constitute new 
attributes of CapillaryPhys, see "nn11" and "nn33" in the attached version of 
CapillaryPhys.hpp. (Note that these nn11 and nn33 can be used to get the bridge 
fluid-fluid interface S as S = 2*nn11 + nn33). This is about post-processing 
only.


The attached README.txt details the role of the .m files and how to use them: 
interested users in the end just need to give a look to, and launch, 
writesCapFile.m.



The core of the work, as usual, is solving the Laplace-Young equation for a 
capillary bridge configuration. The corresponding, quite classical, equations 
appear in solveLiqBridge file/function. There will be a dedicated journal paper 
on this topic, currently under "Minor Revision" review.



These files are ready to be pushed to trunk, together with updated 
CapillaryPhys (see attached), and Law2_ScGeom_CapillaryPhys_Capillarity, in 
order to read the new data (nn11 and nn33) from generated capillary files.


This email is for possible discussion before I perform the commit.


Cheers,


Jerome


PS: Vaclav, I took the liberty cc-ing you since I had once the feeling you 
would be interested in such scripts. (Woo does not include any capillary 
interactions at the moment, though ?)
