Simulation of solids mechanics with impact contact and friction, The Siconos software release 3.5.0

Submitted by vacary on Fri, 11/02/2012 - 20:29

Dear colleagues,

For people interesting in the simulation of solids mechanics with impact contact and friction, we are pleased to announce the release 3.5.0 of the Siconos software. The software is open-source, under GPL Licence and can be found at http://siconos.gforge.inria.fr/

It contains several time--stepping integrators for the nonsmooth dynamics and a large colection of solvers of the frictional contact problems that can be used separately.

Using VUMAT in CEL analysis

Submitted by shapoor on Thu, 11/01/2012 - 14:12

Hi every body

I am trying to use VUMAT in CEL analysis, i.e. eulerian elements. I am familiar with VUMAT in Lagrangian element, but I do not know how it can be done for eulerian or coupled eulerian-lagrangian analysis. any help would be greatly appreciated.

Dear all, I want to simulate forming process with abaqus, and extract the modal frequencies of the formed model. I mean two steps in a single model. Is it feasible? Many thanks for your discussion and help.

viscoelastic modeling in ansys

Submitted by lalkrishna on Thu, 11/01/2012 - 09:28

software

ansys

i am currently doing project using ansys. i have to model the properties of a gel using viscoelastic properties. there are different viscoelastic models in ansys , i dont know which model should use and how we get the parameters for that model.hope a favourable reply

regards
