Finding all roots of a nonlinear function
Forums
I need to find all possible roots of a nonlinear function in six
variables y = f(x_1,x_2,x_3,x_4,x_5,x_6), where 0 <= x_i <=
x_max. The function is not available in closed form. I saw there are
some methods available (e.g., http://www.springerlink.com/content/y8g01h854693g876/). Could someone point me to a code I can directly use ?
Regards,
Deepak
Multiple positions in experiments and CFD
Multiple, assistant researcher/research scientist/postdoctoral positions are available in a large, 4-year duration, Department of Defense program on “Release, Atmospheric Dispersal, and Environmental Fate of Liquid Agents”. The effort is aiming to: (a) achieve a basic understanding of the physics of aero-breakup and dispersal of liquid agents in high-speed flows, (b) achieve a basic understanding of impact/spreading/absorption/reaction/evaporation of drops falling on various substrates, and (c) develop and validate computational tools covering the hierarchy of scales involved and purp

Why Griffith's Law of fracture does not hold at the nanoscale
We know from fracture mechanics theories that fracture instability in a perfectly brittle material occurs when energy release rate (G) becomes equal or more than two times the surface energy (γ) of that material. The value of G = 2γ is known as fracture toughness Gc. This is the classical Griffith criteria of brittle fracture. Experimentally, however, we know that plasticity becomes eminent for most materials and this criteria does not work.
Element free Galerkin method
I would like to know whether any works have been done in EFGM which suggest the best points in the domain where the stresses have to be computed, like in FEM we do have Gauss points which give minimum error for secondary variables. So can any one please suggest some references in this regard?
