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?
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.
