What is CNTSB? Why is is most of the time needed?

Recommended Posts

What is strain energy and contact energy?

 

What does contact stabilize in expert NL card do?

 

What is the difference in using CNTSB in ExpertNL to using the CNTSB card as load collector and adding it to the load step.

 

Thank you!

When a structure deforms, different regions strain by different amounts. The sum of the energy in the structure due to the deformation is called the strain energy.

Contact stabilization energy curve is available from 2017.2 version. Please refer attached video for the CNTSB in ExpertNL to using the CNTSB card as load collector.
