Modul: Import2Mesh
Generate STL - Mesh from Catia, Step, NX and XT(parasolid) file format

Important: Excellent mesh healing functionality!

                                                            3

Estimation of blank holder force
 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

                                                          4

Vegter2017 and BBC2008

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

                                                         5

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

• Create your own databases                            • Improved material search function
• Add, rename, delete, manage your own materials

                                                   7

Disable Auto Positioning

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

                                              Disable Auto Positioning
   Manual positioning in z                    in certain strategies

                                          8

Run to the end
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

                                                         9

Improved contact for „Accurate“

 Stampack Xpress 2020.0 accurate
 Thickness 1.78mm

 Stampack Xpress 2021.0 accurate
 Thickness 1.7mm

                                   10

Postprocess: Curvature Radius in Shell
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

                                                       11

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

         Old thinning scale in shell                New thinning scale in shell

                                               13

Improved Solver Report File

   Added the running mode          Added the already Elapsed Time

                              14

Blank
Faster mesh creation solid with 0 refinement:
▪ In 2020.0: 3min 52s
▪ In 2021.0: 32s

                                          15

Additional Information
           Added Information of the System to make debugging easier

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
