Utilizing Contact Stabilization Damping Properly in Ansys Mechanical - Lesson 2

In engineering simulations, a proper definition of contact is required to accurately model the interaction between two bodies. However, in some cases, components in an assembly may not be touching each other initially. In such cases, the components may undergo some rigid body motion before contact is detected between them which may lead to non-convergence. In this video, we discuss a few ways to resolve this problem and demonstrate the use of one such option, Contact Stabilization Damping, in Ansys Mechanical.

Very nicely presented. Thank you.

[@krzysztofwierzbowski787]

I have already seen some of your video and I must admit that they are very well prepared, the way you discuss the issues is very understandable. Good job!

[@amvali]

Very informative, you should do more of these videos

[@TheMultiLibra]

Great video, with comprehensive guide and explanation. Deserves respect!

[@Max-nb6co]

Sir, THANK YOU SOOO MUCH. I have a shaft to coupling problem with a tolerance gap between the teeth pair and I could not have a converged solution. This helped so much, thank you so much.

I have no Stiffness Energy in the Solution Information context menu. Why?

[@EngineerHarris]

Did you ever find an answer to this? I have the same issue.

[@ThomasHaberkorn]

@@EngineerHarris not really, but I guess my licence level isn't high enough
