FEM

This abbreviation refers to a numerical analysis technique (finite element method = FEM), which is used in product development.
It enables the simulation and analysis of complex structures and components by dividing them into smaller, more easily calculable elements.
By using FEM, engineers can predict the loads, stresses and deformations of molded parts in different environments and conditions.
This is critical for optimizing products and avoiding design errors.

Moldex3D

A leading software for simulation of plastic parts is Moldex3D from the company Coretech System.
It helps e.g. to validate the part design, balance the filling, choose the correct machine, check the cooling layout and warpage prediction.
The results can be exported directly to a structural mechanics program.
The 3D meshing allows simulation of other applications like GAIM/WAIM, Foaming and ICM, next to the traditional injection molding.

Moldex3D Viewer

The usage of the free Moldex3D Viewer software is necessary to look at the results from Moldex3D injection molding simulations.
It is possible to check the used materials and process parameters.
Furthermore, different views, slicing, iso-surfaces and different scaling help to interpret the results correctly.
Animations and screenshots can be easily created for presentations in this software.

Moldflow

As one of the first simulation tools for the injection molding process, the software Moldflow was commercially available.
The company with the same name as the software was founded 1978 by Colin Austin in Melbourne, Australia.
The first calculations where done using simple formulas on plates and cylinders. Soon, the use of FEM technologies and the computation on a midplane model followed.
Based on that, the part adviser, fusion or dual domain technology was developed and implemented in the simulation. Consequently, the simulation technology was further developed into a full 3D approach covering the simulation of the injection molding process as well as all related processes.
Autodesk acquired Moldflow in the year 2008. Since then, the software is known as Autodesk Moldflow.

Node

A point given by x-, y- and z-coordinates in a cartesian coordinate system is named node in finite element analysis.
In a 2D or 2.5D system a node is part of a beam element or a triangle element.
In a 3D system a node is part of a tetraeder, hexaeder or a prism element.
The analysis in a FEM system is normally done from one node to his neighboring nodes.
Calculated results will be assigned to the given node.
