We welcomed over 50 guests to our office in Stuttgart for this year's PERMAS Technology Day on April 3, 2025.

The presentations and panel discussion attracted considerable interest. A broad range of topics were covered. In the panel discussion on "Simulation as a Driving Force for Better Products?", the three experts Prof. Berkemer (Esslingen University of Applied Sciences), Dr. Wierse (SICOS BW GmbH), and Dr. Wehmann (Daimler Truck AG) engaged the audience in a knowledgeable and entertaining manner, moderated by Mr. Fischer (INTES).

After this successful PERMAS Technology Day, we are looking forward to the next event, our user conference in spring 2026!

The new PERMAS/VisPER Version 20 is released!

You can achieve greater efficiency and higher productivity while simultaneously expanding functionality with our completely new MLDR eigenvalue solver. The PERMAS Multigrid contact solver has also been revised to raise stability and robustness to a higher level.

The innovations Harmonic Balance Method (HBM) and integrated fatigue analysis have been significantly expanded in terms of functionality. Of the many other innovations, the stress-based topology optimization and the CAD integration of topology optimization stand out in particular.

Furthermore, VisPER V20 offers extended functionalities in the result visualization such as beam profiles and shell thickness, isosurfaces, many new fatigue life results, orbit and traceline plots and the transformation of results into local systems.

You can find more information about PERMAS V20 here.

You can find even more information in the Short Description und der Product Description in updated form.

We hope that you can use our new innovations with joy and success.

We welcomed over 90 guests from 10 nations on five continents to the Mercedes Museum in Stuttgart for this year's seventeenth PERMAS Users' Conference on April 25th and 26th, 2024. The museum was the perfect setting for INTES' 40th company anniversary.

The lectures met with great interest. A wide range of topics were covered, from static contact analysis to dynamics and optimization to fatigue life analysis. The applications came from automotive engineering, mechanical engineering, aerospace and civil engineering. Nonlinear dynamics stood out as a trending topic. - License Model – FlexMod

The speakers from INTES presented many innovations in PERMAS that offer new, attractive solution options.

INTES would like to thank all speakers for the great contributions and all participants for the interesting discussions, questions and suggestions!

Program of the PERMAS Users' Conference 2024 (April 25. and 26. 2024)

We cordially invite you to the PERMAS Users' Conference at April 25. and. 26. 2024 at the Mercedes-Benz Museum in Stuttgart. We are excited to be able to offer a broad spectrum of interesting topics.

Please note the early bird offer is valid until january, 26. 2024. The invitation may be found here: Invitation
or direcly on our event page.

We are looking forward to your participation! Do not miss the opportunity of a direct and personal exchange.

Best regards from your INTES-team

The conference program will be updated regularly.

We would like to thank our customers and friends for the good and trusting cooperation over the past year.

This year, we looked at the tuning of a tuning fork.

The tuning forks communicate via the surrounding air. By mistuning the material parameters of one of the two tuning forks, we observe an effect similar to that of tuned vibration absorbers. This can be achieved by the sampling procedure in PERMAS.

The animation shows the eigenmode at the fundamental frequency of 440 Hz. The result of the coupled fluid-structure simulation is available as an acoustic signal.

The Python module wavio [3] was used for this purpose.

The simulation has been motivated by LinkedIn posts [1,2].

In order to contribute to environmental protection, we donate to the WWF for the "Stop the Plastic Flood" project to reduce plastic waste in the seas.

We wish you a healthy, peaceful and successful year 2024.

INTES will be represented at numerous events with specialist lectures in the spring of 2023.

The topics range from generative design, additive manufacturing, sampling, harmonic balance method and fast contact solvers to fatigue life calculation.

This are the lectures in detail (events):

• 13./14. March 2023: NAFEMS Seminar "Robust Design & DoE mit realen Defekten" in Munich : "Advanced Sampling Techniques for Synchroneous Whirl of a Rotor subjected to uncertainties" und "DoE To Extend Knowledge about NVH Behavior of Braking Systems" vertreten.
• 15. - 18. May 2023: NAFEMS World Congress in Tampa, Florida, USA: "Design Space Exploration and Optimization of Structures under Consideration of Buckling Conditions", "Contact Analysis in EV Applications", "Generative Design - Topology Optimization from CAD to CAD", "Standardized Testing with Simulation Support in Structural Dynamics", "The Harmonic Balance Method and its Applications in Structural Dynamics", "Product validation with High Performance Simulations", "Benefits from Integrating Fatigue Analysis into the FEM Solver" and "Weight Optimization of Transmission Housings" vertreten.

As the year draws to a close we would like to express to all our customers and friends our gratitude for sharing business with us and for your commitment to our company.

As every year we have tried to virtually work on a seasonal topic.

Harmonic Balance is the topic of this year:

A Christmas bell is rung by a harmonic bouncing of a clapper onto the bell surface considering nonlinear contact conditions. The clapper excites the bell due to a prescribed sinusoidal movement which constant frequency lies near the first resonance frequency of the bell at 110 Hz. All deformation and acoustic results are analyzed by Harmonic Balance Method combined with Time History analysis.

The animation on the left side shows the proportion of acoustic sound radiation power for the forth harmonic vibration of all single frequencies in a range between 90 Hz to 130 Hz.

The animation on the right side shows the ringing of the bell in time domain. Therefore all considered harmonics are proportionately superimposed in one period for the selected excitation frequency at 110 Hz.

In order to contribute to environmental protection, we donate to the WWF for the "Stop the Plastic Flood" project to reduce plastic waste in the seas.

We wish you a healthy, peaceful, and secure new year 2023.
