Modul: Viewer

2

Module Viewer:• Only see the results• Requires licence, but is free of charge

Modul: Import2Mesh

3

Generate STL - Mesh from Catia, Step, NX and XT(parasolid) file format

Important: Excellent mesh healing functionality!

Estimation of blank holder force

4

New option to simulate blank holder without knowing the forces→ The blank holder is a rigid tool that applies the required force to hold the gap

→ Required blankholder force can be seen in the results

Vegter2017 and BBC2008

5

Collaboration with Tata Steel Europe to integrate modern material models Vegter2017 and BBC2008

• More accurate forming results for Aluminum and High Strength Steel

• More accurate Springback results

• Available for Shell and Solid

Benefit:

• Tata Steel material database with 120 material cards

• Development partner with a lot of knowledge

New material supplier

Experimental verified steel data from:

▪ Tata Steel: 135 steel material cards

▪ Salzgitter Flachstahl GmbH: 11 steel material cards

6

Improved Material management

7

• Create your own databases• Add, rename, delete, manage your own materials

• Improved material search function

Disable Auto Positioning

→ Allows the user to position the blank manually for special hand insertion tools

Manual positioning in zDisable Auto Positioning in certain strategies

Run to the end

9

Finish the shell simulation, no matter what happens!• Prevents the solver stop due to “Too distorted

mesh” and “Divergence”• Helps in processes that contain „natural“ problems

like massive wrinkling to come to a result• Helps in difficult Trim Optimization with robustness

problem

Detect cracks in „unsimulatable“ parts

Improved contact for „Accurate“

Postprocess: Curvature Radius in Shell

11

Shows bending radius in the shell simulation:

• Helps to detect non-flat zones in the sheet

• Is a good indicator for markings in the real sheet

Springback

Clamp Radius cannot be defined any more

→By default clamp radius = endElementLength / 10 to simplify setup and to avoid errors

12

Thinning

Thinning result aligned for shell and solid

New thinning scale in shellOld thinning scale in shell

Improved Solver Report File

14

Added the running mode Added the already Elapsed Time

Blank

Faster mesh creation solid with 0 refinement:

▪ In 2020.0: 3min 52s

▪ In 2021.0: 32s

Additional Information

16

Added Information of the System to make debugging easier

Examples for download

17

2 typical progessive dies: Drawing of round part


18

1 Example: Edge Crack

2 Examples for Trim Optization

Heat ExchangerCasing


20

1 example including drawbead


3 Examples: Solid gives excellent results, shell does not show the issue

21

Goals for the next versions

Planned release of 2021.1 in June 2021 containing:

▪ More flexible licencing

▪ Possibility to simulate gravity

▪ Speedup of large shell simulations with drawbead

▪ Include the external tool meshing application directly in Xpress

▪ More flexibility in the blank mesh creation, for example:• Tailored Blank

• Tailored Rolled Blank

• Patchwork Blank

• Chamfered Blank for Eletrical Connector
