Software taylored for machine tool simulation

MORe is a comprehensive software package that allows an efficient and straightforward workflow and features a multitude of analysis options. It has been developed with the specific properties of machine tools and the questions arising during machine tool development in mind. MORe enables you to create a virtual prototype of your machine tool, which can be used for design, control, or trouble-shooting purposes.

More efficient, more accurate

Efficient algorithms for model reduction and modelling of moving interfaces on flexible bodies

Efficient analysis

Easy-to-use and comprehensive analysis tools for the analysis of machine tools in the whole working space

Accurate results

Novel model order reduction method featuring an a-priori error estimation for a specifiable frequency range

Rely on well-established tools -
enhance with cutting-edge methods

MORe interfaces with renowned engineering tools

User interface​

MORe offers an intuitive GUI which allows to create a new model with ease.

Using the Mayavi package for 3D visualisation, MORe offers state-of-the-art visualisation and is easily extendable.

MORe is written in Python and offers a clean API, and can thus be used from the console or be scripted. A mixed workflow with tasks performed with the GUI and repetitive tasks automatised using scripts lets you handle vast modelling problems efficiently.

Exporting a component from ANSYS involves nothing more than running one macro.
