How to create a helical edge in GAMBIT?
> Would you describe a general strategy for constructing and meshing a 3-d helical rod (like a spring) in Gambit? Create a vertex Create a face for helical tube (say inlet) Geometry->Edge->Revolve (first button on 3rd row in GUI) Enter vertex to rotate Angle (say 360 *3 = 1080) Height of the spring and apply You can then create a circle using FACE option and then create a volume using Sweep Face with Perpendicular option along the helical edge. Here is a jou file: vertex create coordinates 0 0 0 vertex move "vertex.1" offset 1 1 0 edge create revolve "vertex.1" height 3 angle 1080 vector 0 0 1 origin 0 0 0 face create radius 0.2 zxplane circle face move "face.1" offset 2 0 0 edge delete "edge.1" lowertopology vertex create coordinates 2 0 0 edge create revolve "vertex.4" height 5 angle 1024 vector 0 0 1 origin 0 0 0 volume create rotate "face.1" onedge "edge.3" draft 0 extended window modify shade |
