1st Stage Lattice Optimization

Andre_1997

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.
