The authors carry out an adaptive refinement finite element analysis for full three-dimensional problems. The adaptive refinement procedure is applied in conjunction with a back interpolation for the construction of a good initial guess for the solution of the system of linear equations. It is shown that these techniques along with the preconditioned conjugate gradient (PCG) solver lead to a significant reduction in the number of operations. Several numerical applications illustrate the efficiency of the procedure.
