FEM Workbench/es

Introduction
El banco de trabajo MEF provee un moderno flujo de Análisis de Elementos Finitos (AEF) para FreeCAD. Principalmente estoy significa que todas las herramientas para hacer un Analisis de Elementos Finitos estan combinadas en una (GUI) Interface Grafica de Usuario.



Workflow
Los pasos para hacer un AEF en el banco de trabajo MEF son:
 * Pre-procesar
 * Modelando la geometria, en ya esta cerca de ser un programa de completo crecimiento
 * Crear un analisis:
 * Crear una malla MEF fuera del modelo geometrico.
 * Agrega un material para el modelo de analisis
 * Resolver
 * Resolver el sistema de ecuaciones dentro de la GUI de FreeCAD.
 * Pos-procesar
 * Ver los resultados dentro de la GUI de FreeCAD.

Como la versión 0.15 de FreeCAD, el modulo MEF puede ser utilizado en Windows, Mac OSX y plataformas linux. Desde que el banco de trabajo hace uso de programas externos, la cantidad de intervención manual dependerá del sistema operativo que estés utilizando.Revisa Instalar MEF
