Hello Folks,
I want to ask you some questions about the comparison between models using shell and solid elements. Enclosed print screen models that I use for comparison
1. If I use the Y axis at the moment of the Coordinate System 1 then great stress obtained almost the same between the shell and solid but the location of maximum stress and the distribution of different mental distress. What causes this difference?
2. Which model gives the correct solution based on contact sets are there?
Thank you and regards,
Can't tell.
Did you refine the mesh on each model until the stresses stop increasing? You need to be sure that coarse mesh isn't causing skewed results.
Refine mesh in areas with high stress gradient until results stop changing significantly. There are options for auto mesh refinement, or you can do it manually.
When both models have reached convergence, then you will have a fair comparison between the two.
