Thank you for the reply.
Sounds interesting.

Thanks, Djordje. 

First, since this project has just began, please join  http://www.grasshopper3d.com/group/ricecooker

and follow the up-to-date information.

The current version is 0.1 but soon (perhaps today) the next version will be released.

This add-on can search shapes in equilibrium. It supports analyses in one, two and three dimensional continuum bodies. They  are discretized in the same manner to the finite element method.

With the terms of nonlinear finite element method, this is just an explicit solver of equilibrium equations of discrete models consist of finite elements. Currently, 2, 4, and 8 nodes isoparametric elements are supported. For example, an 8 nodes isoparametric element (often called brick element) has 9 integrating points and Gaussian quadrature is applied to evaluate integration of virtual work, or equivalent nodal forces. The elements are capable to be combined with three hyper-elastic materials, they are St.Venant body, Neo-Hookean body and Mooney Rivlin body. Also, a special material which can be used with form-finding analyses or geometric optimization is provided. Volume force (gravity which takes density as parameter) cab be also considered. Large deformation, large strain, geometric stiffness are also considered without any tricky technique because this is an explicit solver. No computation of inverse matrices is required so that some parameters can be changed in real-time operation.

In the context of architectural structural engineering, what exactly this is, is just an iterative computation based on the Dynamic Relaxation Method.

Regards.

Hi Masaaki,
What exactly does this add-on do?
