Hello dears

I m new in this forum. I appreciate to meet you in here. 

I have a project. Have to some structural analysis.

 

I wanna show some pictures. First picture is about analysis conditions. How can I distribute these force all surface and tubes ?

 

I tried some analysis and gain similar displacement results. 

 

First I used RBE3 element. After choosing dependent node I used all nodes on the surface. So I did this method 4 times  You can see in second picture.

 

Second I divided surface mesh to 4 parts and  linken force point to quarter surface RBE3 elements.. You can see in third picture what I said  and I appied these forces.

 

I m in doubt all that I did.

 

Could you help me ?

 

 

Regards

    I don't think RBE3 is good choice in your case.

     

    Maybe the good way is :

    • Use PRESSURE on shell
    • Use NODAL FORCES
