1st Stage Lattice Optimization

Hi,

 

I am working on a lattice optimization problem for a UAV configuration and I am getting the following error for a series of grid points to which REB2 and REB3 elements have been attached. There is also a SET defined in the model containing all of these points. 

 

  *** ERROR # 835 ***
  A dependent d.o.f. of rigid elements should not be defined in ASET.
          grid id = 23766106
        component = 1

 

I have an idea of how to fix the issue but I do not want to mess up the FEM file as I was not the original creator. Any pointers?

    Does the original model run as-received?   Did you add the RBE2s?  Is the received model huge? 

     

    If yes, yes, and no ;)/emoticons/default_wink.png' srcset='/emoticons/wink@2x.png 2x' title=';)' width='20' />; then remove all the ASET cards and run the model like you would anything else.

    Could you please share the .out file of the run? Also if RBE3s in the models that is causing the issues then remove and replace it with RBE2s.
