Dear all,

I'm doing a dynamic analysis and optimization of high speed railway bridges. After developing the abaqus input file (*inp), the following errors have occured and I was unable to solve them. I have attached a picture showing the node number that I used to model the train. the car body and the bogies are model as a rigid body in which nodes 6001,6004 and 6501 are the reference nodes. 

1. An overconstraint problem. it says "Zero pivot when processing Node 6004 d.o.f 2, node 6004 d.o.f 6 and node 6001 d.o.f 6

Applications are invited to the Civil and Computational Research Centre, Swansea University, for a PhD in the field of Computational Multiphysics. This project is in collaboration with Siemens Magnet Technology (SMT) and will be funded by an Engineering and Physical Sciences Research Council (EPSRC) case award with an enhanced stipend.

Dear All,

DO NOT write directly to me, but please follow the website.

A post-Doc position is available on a project on Ensemble Monte Carlo simulations of graphene for power electronics applications for studying the effect of boundary scattering of charge carriers in graphene nanoribbons. The project is sponsored by the Office of Naval Research- global (ONR) - Department of Defense (DOD)- U.S. Navy. 

Off late, I am not seing any random thoughts on iMechanica.  This is my humble attempt at reviving such discussions.  Please contribute with your comments...

Bringing together 18 chapters written by leading experts in dynamical systems, operator theory, partial differential equations, and solid- and fluid mechanics, this book presents state-of-the-art approaches to a wide spectrum of new and challenging stability problems.
