Lars-Erik Lindgren, in Computational Welding Mechanics, Dynamic and adaptive meshing. Dynamic and adaptive meshing are methods to concentrate the elements to regions with large gradients. Thus, increased computational efficiency can be obtained without sacrificing accuracy.

Dynamic meshing denotes a technique where the user prescribed the refinement and coarsening of the finite Although the mesh intensity in Eq.

last year i saw two papers which used adaptive meshing. one was by a guy named Danenhoffer who works for Pratt & Whitney/UTRC (in a VKI lecture series book) and another by Bijan Code_Aster book “Beginning with Code_Aster” will help the beginner (and the not-so beginner) to start using this program.
