Creation of an Involute Geometry

Hello
I am trying to create an involute geometry from a set of data points. I input these points into comsol 3.5a but i don't know how to smoothly connect them into the correct shape. I took the set of points i had and created an equation that best describes the shape but i don't know of any way to input an equation into comsol to creat a geometry or if it is even possible. I have looked in several places but they don't talk about different methods to define geometry.
Thanks in advance

Hi
from my understsand so far you can only build your geometry as standard block and bolean operations in COMSOL.
But if you have an analytical expression of a surface, you can use it to have Comsol to deform a plane face into this shape, I beleive it was via the ALE. It's either used as an example in some of the COMSOL multiphysics courses (that I highly recommend for all users, I learned a lot following them) or in the doc, but as I'm out of office, I have neither by me.
Think it over and have a try
Good luck

Hi
they were:
1) part of the COMSOL ALE course I followed in Grenoble a couple of years ago, I can only recommend that you follow some of these courses you learn a lot, even when you beleive you know everything (like me;), I have followed 5-6 and would not mind go back again
2) I beleive (but havnt found back) also in one of the exmples in the documentation, or was it one of the models in the model gallery ?
Basically its setting a prescribed displacement on a boundary of a volume in the ALE module, and have this described displacement being driven by the desired final boundary shape to deform it as desired.
Hope this helps
Good Luck
