I have a model that I am using to validate mechanical testing. I have validate three models up to 5% with a 1.5mm mesh. I have performed a mesh sensitivity study and found that smaller mesh sizes change my results. My model has the correct boundary conditions, correct material properties, etc.. I am trying to publish my paper and wondering if it's common that you can validate a model without mesh sensitivity? If it is not, what is the proper way of performing mesh sensitivity on a corrugated core? I don't want to go smaller in mesh because my models is no longer validated. Thank you.
Mesh sensitivity analysis is a critical step in numerical simulations to ensure the reliability and accuracy of your results, especially when you're dealing with complex geometries and physical phenomena. It's commendable that you've conducted a mesh sensitivity study and observed changes in your results with different mesh sizes. Here's some guidance to consider:
In summary, while it's common to aim for a mesh size that yields validated results, it's equally important to demonstrate an awareness of mesh sensitivity and convergence in your publication. Acknowledge the limitations of your study and discuss how your results might change with finer or coarser meshes. This transparency will enhance the credibility of your work and allow readers to better understand the robustness of your numerical simulations.
@kristaq hazizi, thank you for your response and guidance. Your reply has given me new guidance on my problem.
