Hello There! I did a simple FEA simulation for a sheet metal as a support. I have run the program with different mesh qualities from 5 to 10. But the results show different max. displacement from 0.3 to ~3, respectively. I don’t know which result is good, compared to the reality, because the results have a big gap. How can I judge which result is good ? Thanks in advance!
Can you please provide us with a link to your project?
What I would do is to try to run increasing finer mesh until you don’t see any result changes.
Also, it can be never wrong to do a simplified hand calculation to see in which region the displacement should be.
For a thin structure like this in bending you would need a 2nd order mesh to get correct results.
With that you should see pretty quickly a mesh-independent result.
