Dear friends,

I have created a 3d spiral coil in gambit, now trying to mesh the volume
after finishing the meshing operation the whole geometry shrinks into a 3d shape just like a simple spiral line.

here is the geometry (attach file)

how ever I dont have a screenshot from the meshed status right now
but if you require to see and understand the situation, I can mesh it again and put a screen shot here


thanks in advance.

yes post pictures of the mesh, to understand your problem

Try to split your volume into several maller volumes.
Create one (yz) plane and split your volume with the face.
Then the same with (xz or xy I don't see the orientation).
Finally you have subdomains for each 90° angle.
If you still have problem, try to isolate a smaller portion (45°, or 25°, etc...)

in this way I would have 8 volumes indeed
am I right ?
I must try this , thanks

seems like it just meshes the geometry along a straight line , not a curvilinear one that is my spiral line that a circle line is extruded along.

create a yz-plane (a surface)
split it with your volume.
Theorically it will separate your volume into 2 subvolumes, but in your case you will have more than one subvolume at each side.
You will understand

Splitting the volume was a good idea,
gambit couldn't mesh complex volumes like this.

Thanks mAx it worked.
