In the top of my list "todo" is the implementing "bonded particle schema', like described in http://www.springerlink.com/content/l2306412v1004871/
Vaclav, you think, it is better to implement it in contact geometry classes mostly? ______________________________ Anton Gladkyy 2010/1/17 eudoxos <[email protected]> > > > -------- Original Message -------- > Subject: Re: [Yade-dev] Is shear incremental calculation verified > Date: Sun, 17 Jan 2010 08:44:47 +0100 > From: eudoxos <[email protected]> > To: Bruno Chareyre <[email protected]> > > I was actually thinking about implementing contact geometry classes from > scratch, both incremental and non-incremental versions, in such way that > deformations (normal, shear, twist, bending) would be precomputed in the > Ig2_* functor, and then just accessed directly from the constitutive law. > The InteractionGeometry classes themselves would be the same, only the > functor would make the distinction of absolute/incremental.
