Our PERMAS Technology Day will take place again on April 27th in Stuttgart. You can register online! All information can be found on our event page.

We cordially invite you to our PERMAS Technology Day on April 27th, 2023 at 9.30 Uhr a.m. in Stuttgart.

The event will be held in German and will take place in our office in Stuttgart. For our international users, the PERMAS Users' Conference will take place again in 2024. Contact us today if you would like to contribute to our 40th anniversary in 2024.

In lectures we show a variety of technical applications on current PERMAS and VisPER topics. The event will take place in the office of INTES at Breitwiesenstrasse in Stuttgart. Approximately 30 minutes are planned for the presentations with a short discussion. Questions are welcome directly after the presentations and in one-to-one discussions.

As a further part of the technology day, we would like to talk to our guests about questions and concerns of software users in a TechTalk. We will reserve time for this in the afternoon. We encourage you to participate by giving us your points for the TechTalk on the attached sheet or by email up to one week before the event. We are happy to answer your questions and suggestions.

Participation in the PERMAS Technology Day is free of charge for you, including meals. Registration closes on Wednesday, April 12th.

We look forward to your participation.

You can register online! All information can be found on our event page.

English training courses for PERMAS can be arranged on an individual basis. Therefore we offer the courses at any time convenient to you, provided that an instructor is available. We need to know about the date 6 weeks in advance for planning. So please suggest a date that suits you. Usually, the training takes place in our office in Stuttgart.

We regularly offer regular training courses for PERMAS in the fall. These are then carried out online.

Please note that the language for the regular courses in spring listed on the training page is German and that they take place in Stuttgart unless denoted differently.

We would be pleased to advise you on the ideal selection of training courses.

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.

As reported in the media, there is currently a critical security vulnerability that was discovered in the Java package "log4j" a few days ago.
The Federal Office for Information Security (BSI) classifies this security gap with the highest warning level.
We have checked our products intensively. Neither PERMAS, VisPER nor our tools use Log4j and are therefore NOT affected by this security vulnerability.

The lecture "PERMAS Computes Highly Nonlinear Structures" was presented at the PERMAS Tech Meeting in April 2021.
The presentation is now available in an edited version on YouTube: PERMAS Computes Highly Nonlinear Structures.
Do you have any questions about the lecture or PERMAS?
We look forward to your call or email.

INTES has started a series of five posts about PERMAS contact analysis on LinkedIn.

Contact Analysis? - PERMAS
Do you want to save modelling time by automatic meshing? Specific interpolation schemes will give good stresses also for coarsed (corner node based) contacts.
Are missing initial penetrations hard to handle? This is a frequent problem of contact solvers.
What about contact and large deformations? See animation for an example.
All five pages with a lot of informationen about contact analysis are on our new contact analysis flyer.
Please check also our flyer about Contact Analysis - Fast and Accurate.
