Hello,
I am currently studying the capabilities of SimSolid on different models, by comparing the results with those obtained from classical finite element software. However, I am not always able to obtain consistent results between the two approaches.
There are some parameters that I find difficult to fully understand, in particular the options “Adapt to Thin Solids” and “Adapt to Features.” I have already reviewed the documentation and performed comparative tests (with and without these options), which show differences in global stiffness and local stress results.
But I would like to better understand the internal behavior of the solver in order to determine which parameters to use depending on my model, correctly interpret my results, and justify my modeling choices.
I therefore have a few questions:
- How does SimSolid identify a thin solid or a feature (based on thickness criteria, local stress state, or other parameters)?
- Is it recommended to always activate these options, or can they lead to inaccurate results if the model is not suited for them? If so, how can one determine which parameter is most relevant depending on the model?
- How does the solver treat elements once they are identified as thin solids or specific features?
Thank you in advance for your feedback !
