Hi Pirelli93 & peteroznewman

Sorry Pirelli93, but that is not proof.  Actual proof would be to review the MAPDL input file, ds.dat, that WB Mechanical is writing w.r.t. the beam element definition.  It's using keyopt 3 to change the beam to a quadratic formulation, and is adding the 3rd node at solve.  Mike
