A mini-symposium on Extended/generalized FEM and other partition of unity based methods

mini-symposium 2.14.2

Call for papers

Dear all,



Just in case it is of interest to some of you, we provide links to three postprints related to our Abaqus implementation of the X-FEM. The latest is an "article in press" in Eng Frac Mech where we explain the essentials of the implementation and provide a link to the source code for the Abaqus computation. Note that the implementation is limited to 2D and the pre-processing code needed for element subdivision is not provided.

 

Dear All,



A new multi-million pound initiative to fund research collaborations and improve links between UK and overseas researchers has been launched.



The Newton International Fellowships aim to attract the most promising, early stage, post-doctoral researchers working overseas, who do not hold UK citizenship, in the fields of humanities, engineering, natural

and social sciences.

Dear all,

 Three positions are available for a unique MSC + PhD on massively parallel processing for computational mechanics in the field of multi-scale, XFEM and biomechanics. 

 Details here:  http://www.gla.ac.uk/departments/civilengineering/postgraduatestudy/res…

 Experience in Finite Elements or numerical methods and mechanics is *essential*. Please do not apply if you do not have this experience.

I joined imechanica almost a year ago and I've been frequently following its interesting discussions, even the most animated ones. I think that a place like this is ideal to foster the exchange of ideas in the scientific community;

Moreover it is fantastic as a simple student like me can interact and easily ask questions to the most important researcher in the field of mechanics.

High Performance Computing MSc+Ph.D. position available at the University of Glasgow on Massively Parallel Brain Surgery Simulation with the extended finite element method (XFEM and FleXFEM)  (University of Glasgow) -- funding body is EPSRC.

One year MSc in HPC in Edinburgh (all costs covered by funding) + 3 year Ph.D.  and access to HecToR, one of the world's largest super-computer, including training with experts in massively parallel simulation (10,000+ processors).

I am working on crack propagation . I am trying to figure what factors should be taken into account when the crack is being propagated using XFEM.

I am especially interested to know what happens to the additional dof's corresponding to enriched nodes. Once the crack is propagated and crack tip is at new location , we add new dof's corresponding to enrichment functions , but what happens to the information stored by the dof's of previous enriched nodes,do we forget them altotgether , or do we map it to the new enriched nodes?
