[ICEM] How to create helical tube in ICEM

akbar.mech · March 6, 2018, 05:06

Hi
I would like to know if it is possible to create a helical tube in ICEM. I mean something like the figure attached. I appreciate any suggestions.

1) Create a small round surface (end face or start face) of your helical.
2) Create 4 points that describe your larger helical diameter. Say 0°, 90° 180° and 270°. Make sure you shift the points a bit in vertical distance to follow the helical shape. Let point 0° be the center of your small round surface from step 1.
3) connect the four points by a line.
4) extrude the face a long the line
5) repeat 2, 3 and 4 to extend the helical shape

You might need extra points at the end or start of your line to control the starting angle.

Is your question about creating the geometry or meshing it in ICEM?

If you want to create the geometry, then I recommend using SpaceClaim.

If your question is about meshing it, then perhaps I can help.

Thanks
