I am working with a large \ complex FEM of an aircraft and need to rotate the entire model by 90 degrees (switching from a Y aft to an X aft system due to limitations of another downstream software tool). Unfortunately, I just inherited this model and saw that just about everything is defined in the global CS (referencing an indentical user defined global system from the onset would make such a transformation much easier). This model has a number of local coordinate systems (100+), and better than 70,000 elements comprised of beams, solids, composite shells, CBUSH and CELAS elements... I am fairly new to FEMAP (8 weeks working with it), so I was hoping to crowdsource some tips and tricks for tackling such a problem. Thanks in advance for your support
Solved! Go to Solution.
Use command MODIFY > ROTATE BY > ELEMENT > SELECT ALL and select the axis of rotation & amount of rotation. FEMAP will automatically rotate all nodes which are connected to those elements.
The MODIFY > ROTATE BY > ELEMENT command, unlike the other commands in the menu, will also update the orientation nodes, orientation vectors and offsets of any line elements that you select. This allows you to move those elements as a rigid body, and retain their original characteristics.
Thank you Blas!
The method you suggested saves a lot of work that would have resulted from the use of other methods. There were a vast number of orientation vectors in my model, and this method translated them properly with the rotation. Thanks again for your time & useful advice !
All the best,
