meaning of ea(*,*) and er(*,*) in shell3d.f

[feapnew]

what do these lines do in shell3d.f

!       Construct rotation parameters: u-x = 1; u-y = 2 (same as defaults)

        ea(1,-iel) = 1
        ea(2,-iel) = 2

!       Construct rotation parameters: theta-x = 4; theta-y = 5

        er(1,-iel) = 4
        er(2,-iel) = 5

is the first comment correct, maybe should say displacements.

for user 2d element with nodal dofs x displacement, y displacement, temperature, what values of ea and er should i use to ignore temperature dof in deformed shape plot.

thanks for help.

[Prof. R.L. Taylor]

The values of ea and er are to display boundary conditions.  If you want to ignore a DOF in a deformed plot you set PLOT DOFS 1 2 3  - if any are zero that dof is not used to scale the deform.  So you would set
   PLOT DOFS 1 2 0

thank you professor.
