  1. Define a local cylindrical system for your tube. Presuming that your pressure varies from 0.055 MPa to 0.55 MPa over 180° along circumference, your equation is something like: p = 0.055 + 0.495 * y / 3.14159 ( y = 0.0 .. 3.14159 rad , y is circumferential direction) You enter only right side of this equation into Analysis => Pressure => equation. Don't forget to select your local cylindrical system thanks to the button "system". Load type = PLOAD4
  2. You can use method "equation" or "linear interpolation".
  3. Maybe try PLOAD4 card?
  4. You can make lines/curves/surfaces with Hypermesh. That's not so as powerful as CAD software, but it's ok for your case. Once you have surfaces, the mesh will done for some ... clicks ;-)
  5. Maybe try: Tools => normals => elements => reverse ? Here's my test:
  6. Maybe you forgot "Boundary Conditions"?
  7. I confirm this bug with Hyperworks 2017.1.
  8. Ahhh, that's not legal numerical presentation! I hope staff or Altair's developper could give you some explanations.
  9. Good question! There're some criteria depending to your purposes: Expriences based of similar work ( or feeling?) Precision to got of results analsysis Computing capacity (CPU, memory, disk,...) Ask .. FEA expert
  10. If you can make a mark "by box", do another mark "displayed". The intersection of two marks gives what you need.
  11. Could you share HM model?
  12. Since release v14, Hypermesh writes to "command.tcl" instead of "command.cmf". If you need really "command.cmf" use old release like v13, v12,...
  13. Have a look at Help doc: *settopologydisplaytype Create a TCL script (for example shortcut.tcl) containing the following code : *settopologydisplaytype 1 Preferences => Keyboard settings => Choose shortcut (for example Ctrl-U in my screenshot) and click to find the script "shortcut.tcl"
  14. The first (and basic) rule for any public forum: Never write your message ALL IN UPPER !
  15. Yeah, for "small" & "average" analysis, that's ok. But for "big" (>1.E+6 nodes), maybe you hit Excel limitation
