Hi, Bruno:

I have to admit honestly that I almost got no time to let the yade.0.11.1 version to work with the current bzr (even did not have bzr installed), and I have to say sorry that currently my time that can be spend on DEM and Linux is very very limited (only after work), so after the fluid solver issue (currently still having big trouble with the porosity calculation) is solved I would like to release it in original yade.0.11.1 version form.

I wonder what kind of problem Emanuele Catalano is trying to solve?

BTW: I tested yade.svn1943 last month on my laptop, my feeling is that compiling the svn1943 takes much longer time and consumes more resource on my laptop even for a incremental build which is a little bit frustrating :-)

Hi,

Feng, I was wondering : what is the situation now regarding the 
integration of your work in the current bzr version? I remember you 
planned that. If it is operational, we can plan making comparisons with 
another FVM-DEM coupling Emanuele Catalano is developping now.
