New Features in VisPER Version 6

Great effort has been spent in the past years to provide VisPER (i.e. Visual PERMAS) as a dedicated tool to improve pre- and post-processing for special PERMAS functions. VisPER Version 6 is released at the same time as PERMAS Version 17.

Add&Replace
Add&Replace Wizard.
Model completion
  • Definition and visualization of distributed loads at nodes and surfaces as well as for hydrostatic pressure.
  • Definition and visualization of element reference systems.
  • Extended tree of model information.
  • Local reference systems can be defined for all available coordinate systems
  • Support of function-based contact loads.
Wizards
  1. A new Add&Replace Wizard supports the user in two pre-processing tasks:
    • To add a new part to an existing assembly:
      • Automatic relabeling of conflicting node and element numbers,
      • Optional positioning to correct misalignment, wrong direction, different origin, etc.,
      • Create connections like MPC, contact pretension, pressfit, etc..
    • To replace an existing part in an assembly by a new part:
      • Recover existing sets and connections,
      • Fit surfaces to new geometry,
      • Relabeling of nodes and elements,
      • Manage replaced and new part simultaneously,
      • Keep model consistent.
    DEsign by simulation
    Design by simulation.
  2. A new Design Wizard supports a simulation driven design by generating and smoothing a hull for the topology optimization result, repair the hull mesh, add and checking manufacturing constraints, and generating a TET mesh from the hull:
    • Topology optimization has great potential to create new design ideas,
    • Clear separation of material/void areas essential for automated process to select basic geometry,
    • After having derived a new design, further detailed requirements have to be fulfilled (e.g. by shape optimization),
    • Hence, a simulation process chain has to be followed that best meets the requirements,
    • The simulation chain targets to bridge the gap between topology and shape optimization,
    • The goal is a digital prototype enabling performance based design decisions.

  3. A new Sampling Wizard supports the set-up of a sampling model by preparing the sampling situation, assigning the selected variables, defining the sample value ranges, and specifying the result item for which the sampling should be performed.

  4. A new Pressfit Wizard supports the set-up of a pressfit connection by selecting the pressfit partners, defining the pressfit parameters and loads, and specify the load history, if any.
The already existing wizards have been updated to cover the current state of the PERMAS functions.

Post-processing
  • A great variety of arithmetic operations on result combinations is possible (e.g. difference of kinetic and strain energy density). Each single column may be used as operand. All PERMAS functions with matching number of input parameters can also be used (e.g. logarithmic function to post-process acoustic levels).
  • Merging element node data at structural nodes is now supported.
  • The visualization of tensors has been added.
Tools
  • Using PYTHON scripting enables standardized post-processing including image and video generation. Model information, images, and videos may be exported to MS Word, Excel, and PowerPoint.
