Beam elements which seperate in modal analysis

Beam elements which seperate in modal analysis

Beam elements which seperate in modal analysis

Hi guys,

Does any have any thought why this happens in modal analysis? All elements are beam and is modeled in spaceclaim. all nodes are connected in spaceclaim and there is no gap in model. but when I import it to modal analysis nodes seperate and first and second frequencies bcome zero.

RE: Beam elements which seperate in modal analysis

Can you post a picture of your Spaceclaim model's structure tree.

RE: Beam elements which seperate in modal analysis


Perhaps the two edges isn't exactly coincident in SpaceClaim. Eyes can be deceiving. You try doing this to help diagnose:

In SpaceClaim, try moving an edge of the beam away, then move "up to" back to the other edge to avoid any gaps between the edges of the two beams. Do this for all 3 axes of that edge.

Kind regards,

Thanks sk. Problem solved
