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

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

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

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

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

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
