Excessive Distortion in Press Hardening Simulation

[material_girl]

Hello,

I am trying to simulate press hardening. However, despite what I have tried, I continue to get the warning that my sheet is distorting excessively. I have tried:

• Refining the mesh in contact areas
• Using adaptive meshing
• double-checking the material problems
• changing the load
• changing the die speed
• decreasing step time
• increasing maximum number of steps

I am now trying to run the simulation in Explicit instead of Implicit. However, could anyone please take a look at the .msg file (for implicit) and suggest what else I could try? Much appreciated

You should always check the warnings. Here you have unconnected regions, negative eigenvalues and numerical singularity messages. Check the nodes where issues occur. You can use the Job Diagnostics tool to highlight them. This is easier than reading plain .msg files. Another way is to upload them to "MSG File Analyzer" available online. It will create some plots and highlight the most important information in the message file.
