MS617 Reducing the meshing and remeshing burden in computational mechanics

In recent years much attention has been focussed on reducing the gap between engineering design and analysis. Perhaps the most significant development comes under the title of 'isogeometric analysis' (IA) where the basis functions that are used to provide a representation of the geometry are also used to approximate the unknown fields in the numerical simulation. The field is very active at present, with developments including an extension of the method to fracture modelling with XFEM, cohesive cracks, nearly imcompressible solids, contact problems and Boundary Element Formulations etc.

 

This symposium aims to bring these methods together by classifying them as methods which 'reduce the mesh burden.' This has great industrial significance, and represents a real problem in commercial engineering companies today where significants amounts of time and money are spent on generating and re-generating meshes for numerical simulations. Submissions to this mini-symposium should be submitted which are based on this theme and may include topics such as Isogeometric-FEM, Isogeometric-XFEM, Isogeometric-BEM and other methods which suppress meshing and re-meshing requirements.
