How to define a RWALL

Dear user and support,

 

 

I made a simpel system in OptiStruct: A RWALL which has a certain velocity is moving towards a pipe. My problem is that the RWALL is moving through the Pipe and doesn't deform it. I checked the contact definitions, but I think there are no mistakes so far. What could cause this problem? I can provide the model if you want.

 

Thank you very much!

    Hi the_frik

     

    When defining RWALL have you added slave nodes?

     

    can you please check this?

     

    if this doesn't work, please share the model file with us using the dropbox link in my signature.

    Can you re-create RWALL again and make sure you DO NOT specify any GSID2 in the RWALL card.

    Dear all,

     

    the model/simulation is correct, but Prakash figured out that the problem is connected to the settings. Here the link on how to clear the settings:

    Hi Erik,

     

    One other problem is when you defined the RWALL you have Included GSID2 (In RWALL card) which excludes the node from the rigid wall.

    Hi,

    could I send you another similar problem. The rigid wall can't find the contact, although I had defined one.

    That would help me a lot!

    Thanks,

    Erik
