Hi all,
I recently had an interview for a CAE position and a question that the interviewer asked me which has me stumped. So my project in grad school was about a bicycle frame where I needed to find optimal diameters and thicknesses for the different tubes. The thicknesses of these tubes ranged from 0.889 mm to 3.2 mm. During my analysis I set a minimum mesh size of 8 mm along with a lot of other mesh refinements in areas that needed it. However, during the interview he asked me that if your initial thickness is 0.889 mm, how can you use an 8 mm mesh? That would not work. That got me thinking about it, and I cannot understand how would I mesh this correctly? If I use a minimum size mesh that is equal to the minimum thickness of 0.889 mm, it would lead to an extremely fine mesh throughout the entire part.
Does anyone have an answer to this? How do you mesh 3D solid pipes if the thicknesses can vary depending on the manufacturing parameters that we assign?
I used ANSYS for this btw.
Thanks!
