In the Offshore Structures Earthquake Response simulation, there is a step to enable the mesh based connection before meshing the entire body structure and then resulting in appropriate output values. However, I once tried to do the simulation without enabling the mesh based connection and resulted in natural frequencies data that had a value of 0 in all modes.

 

So my questions are, why do mesh based connections need to be enabled in offshore structure analysis? Is it because of the beam structure in the offshore structure geometry? And if so, should the method always be enabled for beam structure analysis?

Hello Ali, in my opinion, the reason why you have to do a connection is because all the geometries combine into one geometry and are not separated so that it is easier to find out the structural response from the offshore itself. If you don't combine them, the geometry will be considered as different geometries and the vibrations only apply. only on the surface, and on the surface a fixed support is applied, the vibrations that are caused will be ignored, therefore the frequency value will be 0, and Mesh batch connections are activated to support the connection on all connected geometries
