Non Linear Analysis

I have been reading the documentation and the forum on non linear analysis - I just wanted to post up here and check that I have summarised correctly:

 

  1. When using tension only elements (ie cables in my case) the analysis type is forced to 'Static-Nonlin' to account for this behaviour. However, this will not take any account of revisions to the geometry (ie deformations) due to the applied loads.
  2. If I then press 'parameters' and check 'non-linear analysis' this will then cause re-analysis due to global deformation and associated re-distribution of forces.
  3. If I select 'P-delta' individual member actions are accounted for and can be read off if I introduce a series of mid member nodes.

Do I have that about right?
