Thanks

You’re welcome!

hello Dr Jawed Qureshi, thanks you for your video. Can you tell me specifically about the Properties of 3004 aluminum?

[@DrJQureshi]

I got the properties from Euocodes.

Great tutorial, sir! Could you clarify why you prefer using shell elements over solid elements in your videos? Can solid elements be used as well, or is there a specific rationale for selecting shell elements for certain problems?

[@DrJQureshi]

Solid elements can be used as well. But there are two reasons: less computational time and shell elements give better convergence for buckling of thin-walled structures. If a steel tube is filled with concrete, I would use shell for tube and solid elements for concrete.

@@DrJQureshi thank you sir. I tried to model a column using shell and 3d elements. I was getting different Eigen values in both cases. I am struggling to find the reason why it is different. Technically it shouldn’t be.

@@rabinderladhani1294 How much difference were you getting in percentage? A 5% difference is acceptable. If more, then you've to look into mesh sensitivity and other modelling assumptions.

This video was a long time ago, but I hope you see this. When I click mesh controls it gives me an error about 'Dependent part instances cannot be assigned mesh attributes'. You don't see this error in your video. Any tips?

[@DrJQureshi]

Please mesh the parts at part level instead of assembly level.
