โœฆ Synopsis

We address here some computational aspects of the natural-mode ยฎnite element method (NM-FEM), a technique recently developed by the authors for the analysis of arbitrary composite shells. We consider in particular a model problem comprising a 45a ร€ 45a0a90 S cylindrical composite shell with 2398 degrees of freedom subjected to compressive load and temperature increase, and compute the ยฎrst four critical loads and temperatures. For this problem a computational statistics report is obtained showing the breakdown of the CPU time in the various routines. It is observed that most of the computing time is spent on algebraic operations, suggesting computational eciency and high potential for vectorization/parallelization.

We refer to as mixed element/volume (MEV) methods the application of ยฎnite element for diffusion terms and ยฎnite volume for advection terms in a ยฏow model. The compatibility of these methods can be checked for some low-order approximations; the resulting schemes may enjoy the relative mesh-regularit

In this paper we give a numerical method based on ยฎnite element discretizations to simulate the thermoelectrical behaviour of electrodes for electric reduction furnaces. After introducing the mathematical model we take advantage of the cylindrical symmetry of the problem to compute boundary conditio
