12th PERMAS Users' Conference in 2014

Excellent presentations on 30th anniversary of INTES

On May 7th to 9th, 2014, the 12th PERMAS Users' Conference took place in Stuttgart with 160 participants from 13 countries. 21 presentations from different fields covered a big part of PERMAS functionalities.

INTES cordially thanks all presenters and the audience for their participation.

An important part of the conference was dedicated to the new PERMAS Version 15 and the new VisPER Version 4 which will be shipped to the customers soon. Among others major achievements include:

  • Self contact.
  • Force-controlled contact bodies.
  • Linearization of contacts with threshold for subsequent vibration analysis.
  • Multiple temperature changes with temperature-dependent material can be solved in much faster run time (under certain conditions).
  • Post-buckling is now enabled, e.g. with subsequent linear buckling analysis after buckling.
  • Selection of modes for backtransformation after complex eiegenvalue analysis.
  • Export of contribution factors of real modes after response analysis.
  • Essentially reduced run time for direct fluid-structure coupled frequency response analysis.
  • General sampling procedure for one or more variables to make trends visible.
  • Topology optimization shows clear separation of filled and void elements.
  • Shorter runt times for topology optimization.
  • Non-parametric shape optimization for free-form optimization.
  • Use of GPU to accelerate compute-intensive solutions.
