Recently [40], a novel numerical approach, the object-oriented finite element (OOF) [41,42] analysis has been utilized by mapping the real micro/nano morphological images of PP/clay nanocomposites with varied clay contents between 1 and 10 wt%. Such morphological images are captured by two different microscopic techniques, the scanning electron microscopic (SEM) and transmission electron microscopic (TEM) analyses. The tensile moduli of nanocomposites are nmnerically predicted and subsequently compared with the tensile test data. Fuithermore, the available composites models aie used to validate the numerical approach developed in the same [40] study. Finally, the effect of particle distribution on the deformation behavior is also evaluated through the tensile stress and elastic strain contours of such nanocomposites [40]. 

A two-dimensional object-oriented finite element code (OOF2) version 2.0.3 [41], developed by the National Institute of Standards and Technology (NIST), USA, was installed in a Fedora Red Hat Core 4 Linux system. All finite element analyses were conducted on a Dell INSPIRON 8600 laptop with the dual boot system of Windows XP and Linux using 1.6 GHz processors and 2 GB of RAM.

Abstract This contribution deals with the modeling of coupled thermal (T), hydraulic (H) and mechanical (M) processes in subsurface structures or barrier systems. We assume a system of three phases a deformable fractured porous medium fully or partially saturated with liquid and a gas which remains at atmospheric pressure. Consideration of the thermal flow problem leads to an extensively coupled problem consisting of an elliptic and parabolic-hyperbolic set of partial differential equations. The resulting initial boundary value problems are outlined. Their finite element representation and the required solving algorithms and control options for the coupled processes are implemented using object-oriented programming in the finite element code RockFlow/RockMech. 

RockFlow is a simulator that is used to model near-field situation of the type described above (Kolditz et al. (2003)). It is a finite element code, programmed using object-oriented techniques. Object-orientation allows a wide spectrum of applications for the code, and also simultaneous code development (Kolditz (2002)). This paper... 

This paper presented the thermo-hydraulic (TH) coupled finite element model that we developed within the object-oriented simulator RockFlow. The governing equations, their numerical implementation, and the algebraic equations, as well as available coupling schemes for the RockFlow TH model were presented. 

EChem++ [9, 14] is based on adaptive finite elements. Both reaction mechanisms and experimental conditions (such as the potential or current program applied to the electrode as an excitation of the electron transfer processes) can flexibly be formulated. It is an open-source program maintaining principles of object-oriented software design [21] and is under continuous development.
