We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Could give me some hint because I'm not LS-DYNA user. What do you mean 'replace'? In LS-Dyna Restart I set restart type to 'full' because other wise I cannot define boundary condition 'remote displacement', which is the only way I found correct to define rotation with given rotating axis.

When I set supress/unsupress contact, the previous LS-DYNA schematic (E5) gets flush out and need resolve. 

When I go to environment -> conditions ->contact step control. It's greyed out.

When I select a bonded contact and go to LSDYNA pre ->contact property, only 'death time' is availble. What I need is birth time. While frictionless/frictional  contact has much more control than bonded contact.

My version is 2023R2. Hope I was operating something worng. Thank you.
