Reply To: Why DOF is looks like 3 DOF?(Modal Analysis with Linear)

[dhulee]

Hi Erik!

Thank you for letting me know which part of the helper manual it is.

Therefore, it was found that the existing shape was extruded with a beam and had the same frequency in nodal solu.

However, the number of elements is the same as 21, but the number of nodes is 43.

 

I set it to be am at 3 degrees of freedom of solid and made it into 6 degrees of freedom, but I'm looking for why the number of nodes is different.

Can you help me with this part, too?
