Summary:

Much of the recent work by the author [1, 2, 3, 4 and 5] as well as others [6, 7, 8, 9, 10, 11 and 12] has focused on the need to consider idealization geometry a variable in the finite element solution procedure. Such solutions, in which grid geometry is included as a solution variable, have become known as optimum grid solutions.To date, considerable emphasis has been placed on establishing criteria for the selection of optimum grid solutions. Criteria have been successfully established for the elastostatic, elastodynamic and the elastic stability problem [5]. Focus is now being directed at exploring the benefits of utilizing optimum grid solutions. Several papers have communicated techniques for determining "near optimum" meshes [4,12].The purpose of this paper is to consolidate and present the recent advanced made in the area of optimum grid solutions.The author has arranged this talk into three subareas that serve as objectives:Throughout this talk simple example problems will be presented that demonstrate the nature of the process being discussed.Guidelines regarding convergence, error analysis, and error detection as they are relevant in the optimum grid context are included
