Application of finite element method and heat conductivity transfer model for calculation of temperature distribution in receiver for dish-Stirling concentrating solar system is described. The method yields discretized equations that are entirely local to the elements and provides complete geometric flexibility. A computer program solving the finite element method problem is created and great n...

due to the algorithmic simplicity, cellular automata (ca) models are useful and simple methods in structural optimization. in this paper, a cellular-automaton-based algorithm is presented for simultaneous shape and topology optimization of continuum structures, using five-step optimization procedure. two objective functions are considered and the optimization process is converted to the single ...

Nonlinear elastic materials are of great engineering interest, but challenging to model with standard fi nite elements. The challenges arise because nonlinear elastic materials are characterized by nonconvex stored-energy functions as a result of their ability to undergo large reversible deformations, are incompressible or nearly incompressible, and often times possess complex microstructures. ...

DIME is a programming environment for manipulation of irregular triangular meshes with a distributed memory machine. We have added a software layer DIMEFEM which manipulates Finite Element representations of functions and allows the stating and solving of variational statements. An application of DIMEFEM is an incompressible Navier-Stokes solver with a three-stage implicit time step, using quas...

In this work, we propose a mixed finite element method for solving elliptic multiscale problems based on a localized orthogonal decomposition (LOD) of Raviart– Thomas finite element spaces. It requires to solve local problems in small patches around the elements of a coarse grid. These computations can be perfectly parallelized and are cheap to perform. Using the results of these patch problems...

In this paper, we have modeled and simulated the magnetic field of conductor by using finite element method, which is incorporated in Ansoft Maxwell software. Modeling simulation are done for a two conductors located at small distance between them. Our study based on method elements Biot-Savart law calculating depending from conductor. We observed that calculated values good accordance with [1]...

In Liquid Composite Molding (LCM) processes, a fabric reinforcement is placed in closed cavity and resin injected into the mold. Almost all reinforcements are dual scale containing fiber tows, which fill at different rate than region between tows. Simulation of LCM processes can help identify regions that fail to fill. However, presence flow usually neglected. Here this phenomenon modeled using...
