Update: The position has been filled; thanks to all who responded.
A post-doctoral position is immediately available at UC Davis. The individual will work on a joint project led by myself and John Pask at LLNL on the development and application of a new finite-element based approach for large-scale quantum mechanical materials calculations.
I am Ramin Aghababaei , new PhD student at Mechanical Department of National University of Singapore. My thesis is about finite element modelling of nanocomposites. Because I am at the first way of my research, I want to know more about my research topic and know exactly why I want to do or what is the problem and how can I solve it? So I have some questions and your experience is invaluable for me in this way. 1-what are the important parameters in the modelling of nanostructures which must be considered?
Finite Difference Method (FDM) and the related techniques such as FVM, are often found put to great use in fluid mechanics. See any simulation showing not only streamlines but also vortex shedding, turbulent mixing, etc.
Comments and feedback of the following paper would be appreciated.
Abstract:
A new technique for the modelling of multiple dislocations based on introducing interior discontinuities is presented. In contrast to existing methods, the superposition of infinite domain solutions is avoided; interior discontinuities are specified on the dislocation slip surfaces and the resulting boundary value problem is solved by a finite element method. The accuracy of the proposed method is verified and its efficiency for multi-dislocation problems is illustrated. Bounded core energies are incorporated into the method through regularization of the discontinuities at their edges. Though the method is applied to edge dislocations here, its extension to other types of dislocations is straightforward.
