Automatically connect any loose nodes on beam elements to shell elements

Hi,

 

If you imagine a square plate with beams running through at various directions, you will note not all beams nodes may overlap the nodes of the square shell elements. I am wondering if there is a way to quickly connect all the beam elements to shell elements without having to create an RBE3 for each node. Perhaps an MPC for two components?

 

Thanks in advance.

    Hi, 

    Can you share the model file ?

    Hi,

     

    Please see attached. I want to attach all the beams to the shell elements without equivalence. 

     

    Thanks

    Hi,

     

    tie contact can be used in Linear Static Analysis (STATICS) and Small Displacement Nonlinear Analysis (NLSTAT). Penalty-based and MPC-based TIE contacts are available and can be selected using CONTPRM, TIE.

     

     

    Connectors can be used alternatively. Refer to tutorial HM-3400: Create Connectors.

    Hyperman,

     

    The help is greatly appreciated thank you. If my plan is to convert the model back to RADIOSS, which of the two options is recommended? Considering connectors are a HM feature, will they be compatible in both solvers?

     

    Also, don't mean to be a pain but if it isn't too much to ask: can you upload a 2017 version of your file?

     

    Thanks again

    You're welcome.

     

    Actually, tie contact can not be automatically converted with tools>convert>Optistruct>to Radioss while connectors elements like CWELD can be converted. Type 2 tied contact is tie contact equivalent in Radioss and can be easily recreated. 

     

    I am not sure how to export version 2017 compatible model but here is the solver deck:
