PRESENTATION OF THE NEW
RELEASE 2.0.5

MTD SA, Route de Muraz 16, CH 3960 Sierre,Switzerland info@m-td.com / www.m-td.com
3D Simulator is simulation software developed by extrusion experts for dies makers and
extruders.
3DS enables the user to perform fast three-dimensional simulations of the extrusion
process enabling one to compute stress and deformation, temperature and fluid flow.
Costly and time-consuming die trials on presses can be replaced by virtual prototyping and
testing with computers. Numerical trials allow selecting optimal CAD concepts. This leads
to savings on correction costs and longer lifetime of critical parts.
Efficient computer simulations with optimized algorithms enable the user to visualize and
understand extrusion material flow, temperature, pressure, mechanical and thermal loads,
as well as to design robust die sets by accurately predicting deflections and stresses due to
these loads. It enables the user to minimize the die design to prototyping time and reduce
the associated costs and overall product development cycle time.
The general presentation is still available on the Slideshare :

INTRODUCTION

The new release introduces new preparation and mesh interfaces that provides to the user
a faster and easier approach in using 3DS.
 Preparation process has been completely automatized
 Mesh process has been simplified, the user just has to focus on mesh density
definition.
 The analysis phase has been completely automatized, views for report are generated
automatically, the user can focus on detailed analysis through a simple « click ».
Time spent to prepare the simulation has been strictly reduced.
The user just has to focus on « productive » phase only
Integration with CAD software is facilitated
WHAT’S NEW IN 2.0

Symmetric simulation is now available :
 Use half model cutting in X or Y plane
Benefit
Simulation time is strickly reduced
WHAT’S NEW IN 2.0.5

It is now possible to continue a mechanical analysis after Aluminium flow analysis:
 In the olde version if you made an
aluminium flow analysis and you want to
proceed to a mechanical analysis, it was
necessary to restart completely the
preparation phase
Now it is possible to continue the preparation
phase with only the die
Preparation time is strickly reduced

3DS supports bearing with variable length on the entry side

CAD PREPARATION
CAD model
Geometrical model is designed and generated as
before
Geometrical and process parameter are written in a csv file.
This file can be generated through a simple Excel or automatically
generated by CAD software and/or PDM system using specific
development

SIMULATION TYPE SELECTION
The main window has been simplified
Old version New version
Define case by selecting the folder
Define simulation you want to proceed in 2 click
And apply selections

SIMULATION DATA PREPARATION
Old version New version
Instead of proceeding step by step, the data preparation phase is done in
background. The user just need to select the parameters file (csv file) and
geometrical files necessary to the simulation

SIMULATION CALCULATION
The simulation interface has been simplified.
Boundary conditions are directly read from
parameters file.
It is not necessary now to proceed to
postprocessing step between each
simulation
Old version
New version

SIMULATION RESULT ANALYSIS
It is not necessary now to proceed to
postprocessing step between each
simulation this done automatically after each
simulation calculation
3DS generates automatically data necessary
for the next simulation step and views that
can be directly integrated into simulation
report
OLD VERSION

SIMULATION RESULT ANALYSIS
An single button is used to visualize results
and to proceed to detailed analysis
