I am trying to estimate the forces it will take to break the Rivets. The run time is too high. I created a simple model to demonstrate the issue with my setup. Attaching the dummy model that recreates the error. Need help fixing the issues in my model.
Timestep in explicit analysis is derived from:
smallest element size/ SQRT(Modulus/Density)
Your mesh is too poor in quality to work well and leads to timesteps of order of magnitude 6e-12ms
In attached version, I roughly remeshed your 'strap' to be better mesh and made the 'tube' rigid, since it looked like that was what you were trying to do with it anyway? I also added mass scaling to raise timestep to 1e-3ms (it adds 180% mass, but since the model is quasi static, this should be ok.
I would recommend reading the Radioss E-book : ebook
Or following some of the tutorial examples in the help as an introduction to explicit analysis
Thank you Paul for the suggestions. Indeed after incorporating your suggestions (I remeshed the models carefully, and also specified minimum time step), the model runs a lot faster. The ebook is very useful especially for me since I am learning Radioss.
