VisPER (Visual PERMAS) is a dedicated GUI to improve pre- and post-processing for PERMAS.

For further informations, see product description.

VisPER, Overview

VisPER (Visual PERMAS) is a GUI based model editor with python scripting for automation. It is used to complete finite element models for specific applications with PERMAS. To this end VisPER fills efficiently the gap between FE models generated by a standard mesher such as Medina and PERMAS models which are ready to run. VisPER can also be used for model verification and post-processing tasks.

A specific user interface greatly simplifies the modeling and hence increases the efficiency of the user. VisPER directly accesses the PERMAS data structures achieving an unmatched data consistency between graphical user interface and PERMAS. In the future, new functions in PERMAS will be supported by the preprocessing earlier than today. Further concepts of the software are:

  • Wizards guiding the user through the respective modeling steps.
  • Scripting (using Python) for the creation and replication of standard procedures.
  • Batch capability, i.e. an interactive process is not necessary for the use of the graphical capabilities.
  • A high degree of configurability allows the customization including client-specific help functions.
Functions for post-processing including animation complete the graphical capabilities.
VisPER supports the following PERMAS analysis types:
  • Optimization for topology, sizing, (free-) shape, bead design
  • Design by simulation (Design wizard))
  • Brake squeal
  • Fluid-Structure-coupling
  • Contact analysis, including pressfit, pretension
  • Model variants (Add&Replace Wizard)
  • Sub-Structuring
  • Model validation (including the execution of PERMAS test runs)

VisPER is a registered trademark of INTES GmbH.

PCGen: PERMAS Component Generator

PCGen is a model generator, integrated to VisPER and specialized in quasi axisymmetrical structures. Although it generates meshes, PCGen is not a mesher. It aims at creating complete F.E. models with automatic nodes and elements sets, materials, properties, loadings (for example pressure in tanks and boosters) and analysis situations. Its primary purpose is to reduce the complexity of the whole F.E. model creation process, so it generates also automatic plans and reports.

PCGen is not an all-purpose mesher, it is a specialized tool, that aims at integrating standards for model generation, as well as providing a convenient and adapted interface for model definition. Thus, it focuses mainly on the following products:

  • Shell structures
  • Laminate
  • Flanges and stiffeners
  • Bolted flanges
  • Fluid tanks
