New Features in VisPER Version 5
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 5 is released at the same time as PERMAS Version 16.
- Definition of dynamic model properties:
- Linearization of contacts by locking contact regions according to contact results,
- Definition of damping,
- Specification of dynamic loads (like inertia loads and loads in frequency and time domain),
- Definition of frequencies and rotational speeds, where the user wants to see results.
- In case of dynamics in modal space, the definition of additional static mode shapes is now supported by VisPER, too. It supports all sources of additional mode shapes like element forces, direct input of displacements or load cases, reference to already available results, or displacements from an inertia relief analysis.
- Comprehensive extensions were made for the handling of functions. A dedicated dialog supports the definition of functions using all PERMAS capabilities like library functions, tabular functions, chaining and summing up of functions, and user defined functions. The defined functions can be directly visualized. A referencing mechanism can show the user, where the functions have been used.
- Material reference systems for orthotropic or anisotropic materials as well as for laminate materials are now supported. The related dialog supports the definition of material reference systems and provides information on existing material reference systems. The reference system and the related structure is visualized.
- All local system definitions are supported by a special dialog. This includes all new system types introduced in PERMAS like cartesian, cylindrical, conical, spherical and toroidal systems. Special visualization facilitates the identification of the particular system.
- A new dialogue bar has been introduced to support the definition of design constraint functions.
- A new Brake Squeal Wizard allows an easy description of complex brake models according to PERMAS
brake squeal technology.
The key features of the wizard to provide model standardization and to ensure process stability are:
- Fast setup of brake squeal analysis,
- Guided definition of additional physics for the dynamics of the analysis task,
- Checking of dynamic definitions and their compatibility,
- UCI file generation after wizard completion.
- The Pretension Wizard has been extended to detect holes for screw candidates.
- The new binary results file in PERMAS (using HDF5 format) can be used with VisPER in order to reduce the time for loading the results.
- For the export of the model after model completion, several selections are available: complete model, new items only, and one single component only. All referenced data will be exported, too.
- A new user result item has been specified, which can be postprocessed by VisPER. This result item follows syntax rules of PERMAS results and is currently restricted to nodal results. Several scalar values at nodes can be used. The results can be generated by any other standard or user written software.
- In order to reduce the complexity of the PERMAS user control, the use of predefined UCI templates is facilitated. A comprehensive dialogue is available to create and modify UCI templates and to use them in the following PERMAS runs, or to store them as new templates for future use. In this way, the flexibility in controling a PERMAS run is very much increased. The use of UCI templates helps to standardize PERMAS user control and minimizes erroneous PERMAS runs.
- A quick exploration of model item relations is supported by a new referencing button. By this button, all model entities are listed, which reference a given seed entity. From the entries of this list, one can directly open the related GUI, or directly visualize the model entities, or select the model entities for further operations.
