HELP ERROR : ROTATED NODES

HELP ERROR : ROTATED NODES

HELP ERROR : ROTATED NODES

(OP)
Hi all:
a question .why when run the ansy/lsdyna appears ITS ERROR:
 *** ERROR ***                           
 Rotated nodes are not permitted for LsDyna Elements.

WHYYY???

Thank for the answer.
  

RE: HELP ERROR : ROTATED NODES

Dyna only supports nodal coordinate systems oriented in the global cartesian system, or CID = 0.  If you provide a better description of what you're attempting that would help us to better help you.

RE: HELP ERROR : ROTATED NODES

Before you solve or write a *.k file in /PREP7 do the following:

CSYS,0
nall
nrot,all

This will correct the issue.  If you need to rotate nodes to create constraints or couples you will need to figure out a work around which is kinematically equivalent.  Dyna has many options available.

Also, it looks like your model is symmetric about the XY plane...why don't you use symmetry?
