VISI: What's New in VISI v.2020

VISI 2020.0

The 2020.0 release of VISI CAD/CAM improves the mold and progressive die design processes, along with enhancement to the Reverse module, specifically designed for the mold and die market.

Part Unfolding

New part unfolding technology has been introduced in VISI 2020.0, giving the ability to work directly on the original solid part without needing to extract the model’s skin.


Sheet Metal Part Recognition

The sheet metal part recognition now provides an improved graphical representation of the part analysed, by identifying bends, planar faces and features. The advantage of the new technology is its associativity with the original model during the die design process, as it allows the original part to be edited, and changes to be made automatically on the study of the part.


VISI Reverse

Enhancements to the Reverse module provide new functionalities for both Reverse and Casting processes, giving greater flexibility for both processes. Features such as clipping plane management for point scanning, planar face and draft analysis on mesh data, adapting a mesh to a boundary, and best fit, improve the reverse process from point scanning to solid model generation, and manufacturing.


Compare Feature

A new Compare feature lets the user compare two entities, such as a point cloud, mesh, or solid, by checking the relative distance – the graphical results show different colors in reference to the distance ranges.  The system also shows the relative distance between the two selected entities during the comparison, by simply selecting a point.


Meusburger Mold Tool Templates

Additional Meusburger Mold Tool templates (FB, FM and FW types) are now incorporated, including new plates as well as standard components. The new mold templates also include assemblies from the same supplier.


VISI Flow Analysis

VISI’s Flow Analysis has been improved by new mesh group technology specifically designed for FEM analysis. It gives a high quality mesh, while reducing computation time, by providing new options to adapt and fit the mesh accordingly to the model’s shape. It’s possible to control the mesh orientation, the curvature of the model, and smooth the mesh on the transition area, leading to a higher quality, accurate Flow Analysis process.


VISI Flow Lines

The flow lines in VISI 2020.0 can now be shown, highlighting possible ‘hesitations’ of the filling from isochrones. This is especially important, as hesitation occurs when the melt flow slows down or stops along a particular flow path, leading to possible asymmetrical and unpredictable flow patterns which can reduce part quality, caused by variations in surface appearance, poor packing, high stresses, and non-uniform orientation of the plastic molecules.


VISI Flow Thermal Function

With thermal analysis becoming increasingly more important in optimizing mold cooling, the Flow Thermal function has been enhanced by improved coolant flow rate suggestions, giving an indicative value for a single cooling circuit, and an improved solid mesh definition for the mold cavity block, along with each axis, to offer more accurate results.


Digimat Direct Interface

Thanks to a new direct interface between VISI and Digimat, data showing material local rigidity can be exported into Digimat for the structural FEM analysis process. MSC Software’s Digimat positions itself between the manufacturing and structural analysis by allowing chosen composite materials to be added to a new reference model to simulate and predict the molded part’s mechanical properties. By bridging the independent Flow injection molding and structural analysis environments such as MARC, APEX and ANSYS, Digimat provides added value with a more realistic stress analysis simulation. Extra data has been added to the material database to better match fibre characteristics, including information such as shape and length of the filler.


Overall benefits include:

  • Realistic structural analysis simulation
  • Influencing design construction to improve the molded part’s mechanical behaviour
  • Optimizes material selection and fibre properties to improve mechanical resistance
  • Validate the part’s properties in reference to the mold design.
