Re: [Yade-dev] recent changes in TriaxialCompressionEngine


 Ok i under take to correct and add comments in the
TriaxialCompressionEngine files as soon as tomorrow with a new commit. Of
course, i will do a svn up before my modifications, after i verify YADE
correctly built.  

>Changing inputFile to TriaxialGenerator is certainly bad idea 

 Question for Triaxialtest users: Can i keep my inputparameters (for
example:isotropiccompression, translationspeed, fixedporosity) in the
generator file to realize directly the isotropic compaction by moving the
walls until a fixed porosity value ?

Thank you

No problem with the code commited, I think that we can keep it, because
it can certainly be useful, it will be ironed our progressively. Unless
you really want to revert your changes, which should be quite easy --
svn has all the history.

Nice explanation. Now just copy&paste that to
TriaxialCompressionEngine.hpp, to the big comment before "class
TriaxialCompressionEngine :-)
