Reply To: ERROR in transient analysis

[dlooman]

Sorry, I tried to reply from my phone, but apparently that's not possible.  What I said was that the E command is much more common than EN.  The element number isn't specified with the E command.  Just issuing solve instead of lswrite and then lssolve is recommended.  RBE3 is a good way to attach a mass to the model.  It's thought of as a force (mass) distribution construct and that's perfect for your application.  I was skimming your input and thrown off by your description of RBE3 as linking nodes.  Because of your use of older commands I was thinking possibly the error you are getting is due to using an old version.  What is the current error message?
