  1. This can be done in CATIA. i joined the small surfaces in CATIA. try joining using join surfaces icon (needed to be done several times) then make it as a solid.
  2. try using spline/filler option in surface panel.
  3. It is always better to give compliance or vol or volfrac as response. If you give stress as constraint it is not necessary that you have to give response as stress.
  4. it is not necessary to have PSD data. in excel sheet create a sine curve with amplitude F. F * sinA, A 0 to 360. then save it as .csv file. now you can do fatigue calculations as usual and use this excel sheet instead of PSD data.
