Generate fluted pipe geometry in ANSYS

Click For Summary

Discussion Overview

The discussion revolves around generating a spirally fluted pipe geometry in ANSYS, focusing on the creation of the cross section and the sweeping process. Participants explore different methods and suggestions for achieving the desired geometry.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant reports difficulty in creating a spirally fluted pipe, suggesting that the issue may lie in the cross section or the sweeping method used.
  • Another participant points out that the cross section has a sharp step, indicating a potential problem with the design.
  • A different approach is proposed, suggesting that the shape can be created by drawing a specific cross section and then rotating and translating it, merging the join line and trimming the ends.
  • One participant recommends trying a cross section similar to a valve cam on a car as an alternative design.

Areas of Agreement / Disagreement

Participants express differing views on the appropriate cross section and methods for creating the desired geometry, indicating that multiple competing approaches remain in the discussion.

Contextual Notes

Some assumptions about the design requirements and the specific characteristics of the fluted pipe may not be fully articulated, which could affect the proposed solutions.

I am trying to make a spirally fluted pipe in ANSYS. I made the cross section as in the attached figure and sweeped on a straight line perpendicular to plane of the cross section. However I get a sort of a drill bit instead of the required spirally fluted pipe. Is there an issue with the cross section or the way I sweep ? Also is there in blog/forum for help on ANSYS issues. Thank you very much in advance

You cross section has a sharp step in it. That looks wrong to me.

That shape can be generated in several ways but one way is to draw a cross section of one half trough + one full lobe + one half trough and then rotate and translate .

Merge the join line and trim the ends flat to complete .
