✦ Synopsis

A h-adaptive "nite element strategy for acoustic problems is presented. The key features of the strategy are error estimation, adaptive mesh generation and remeshing, "nite element analysis. The error estimation has been performed using the superconvergent patch recovery technique for prime variables of "nite element approximation (SPRD). For adaptive mesh generation and remeshing, the commercial software package I-DEAS has been applied. Finite element analysis has been performed using commercial software package SYSNOISE. Numerical examples are shown to illustrate the properties of the SPRD technique and the procedure of the proposed adaptive strategy.

By establishing the appropriate dual problem in space–time, it is possible to establish an exact __a posteriori__ error representation formula based on residuals and the dual solution. In particular

## Abstract Simulation of multiphysics problems is a common task in applied research and industry. Often a multiphysics solver is built by connecting several single‐physics solvers into a network. In this paper, we develop a basic adaptive methodology for such multiphysics solvers. The adaptive met
