A regional mapping procedure for finite element mesh design
Abstract
Practical algorithms for automated mesh design in finite element stress analysis are developed. A regional mixed mesh improvement procedure and a regional mapping procedure are considered. The error control, algorithm implementation, code development, and the solution accuracy are discussed. Numerical examples include automated mesh designs for plane elastic media with singularities. An extended application of the mapping procedure is to incorporate the mesh design with an explicit time integration method for a moving mesh region to handle stress and strain discontinuities at the wave front due to impact loadings. Examples for an elastic wave propagating through plane media are presented.
