✦ Synopsis

This paper presents an adaptive ®nite element method to solve forced convective heat transfer. Solutions are obtained in primitive variables using a high-order ®nite element approximation on unstructured grids. Two general-purpose error estimators are developed to analyse ®nite element solutions and to determine the characteristics of an improved mesh which is adaptively regenerated by the advancing front method. The adaptive methodology is validated on a problem with a known analytical solution. The methodology is then applied to heat transfer predictions for two cases of practical interest. Predictions of the Nusselt number compare well with measurements and constitute an improvement over previous results.

An rh-method, which combines r-and h-methods, is proposed for cost-eective adaptive FE analysis in twodimensional linear elastic problems. Through various numerical test examples, the rh-method is compared with the h-method. From these examples it is concluded that the rh-method has the advantages o

This paper presents a force-based finite element method that involves eigen-space transformation of element stiffness matrices in the first analysis. In each subsequent analysis ('reanalysis') associated with structural variations, the solution obtained previously is modified making use of intrinsic
