Subject: [Yade-dev] Capillary 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 ?)
