Split Object in symmetry for mesh

Hello,

 

I am trying to solve an analysis but my model is very large.

To save on the number of nodes I want to split my model in 2 (since it is symmetrical) but I cannot find the right topic in order to find out what I should do (what to assign) to the nodes and elements in the symmetrical plane.

 

I have found RBE2 and 3 options but I am not sure.

 

It will be the front section of a ship, which I want to split in the middle to perform optimization topology onto.

 

Does anyone know a topic to lookup for the right steps?

 

Best regards,

 

Joep

    Hi Joep,

     

    are the loads applied on the model also symmetry?

     

    Thank you
