Dear Prof. Taylor, dear others,
although I replaced my older version of presld.f with the one you provided here, my results of the 2d simulation do still not agree with 3d. I applied the same pressure from the inside and the outside of a tube and in addition an axial displacement. For the axisymmetric analysis, the radial stress does not equal the applied pressure; in 3d the results are as expected. I attached the files for reference.
I am using FEAP version 8.2. Are there any other changes since 2012 relating to follower loads in combination with axisymmetry?
Once again I would appreciate your assistance.
Kind regards, aza
