Weldments joints simulation problems

Ropanzer Ropanzer Oct 25, 2012 11:09 AM

Hello!

Please help me on this project made from weldments, I have problems with joints.

I attached the part to this message.

Thanks in advance!

I tried opening your Zip file, it contains nothing, can you re-zip your files again.

    Can you briefly describe your problem, i am using SW2011 and was not able to open your file.

      It's to complicated.

      I fix the problems, it works, and after I put all forces on the part after I run the simulation it says that: Model is unstable, restraints may not be adequate. Why? I don't understand I put "Fixed Geometry" in 3 joints.
      Please help! You have attached the new part.

        Well did you define your connections? Fixed geometry is not adequate input incase of multi body part.

        And what I should use instead of fixed geometry

        Well, fixed geometry is one boundary condition that you will need. Additionaly, if you have beams joined together then you have to define how they are connected using "Connections". I think it would help if you can attach some pictures of your weldment.
