Hello
I am trying to simulate a 3D spiral inductor, but I cannot find the right geometric shapes given in Comsol 4.3a to build this coil. I have attached an image of the intended coil I want to build
I have tried using Helix but the geometry is completely different from the spiral inductor.
Any thoughts that how I can simulate it or I have to import it using some other software. Suggestions and advices are welcomed

Khalid,

Have you considered defining parametric curves? Right-click on Geometry 1 and select Parametric Curve. Then, in the edit field you can define expressions for your x and y coordinates based on a parameter s. You will need to know/develop the mathematical equation for the spiral edges in this case. Then, you can use Bezier Polygon line segments to connect the ends. And, then use a Conver to Solid operation to convert the edges into a solid body.

There may be a simpler way to do this, but this is the first that comes to mind.

Khalid,

is this similar to what you need?

Yes its quite the same, except the number of turns are higher than this.

I have tried using archimedes spiral but that is different in geometry, in addition the equation given in most places are for 2D. I am trying to work on equation to get the geometry
