Predefined Curves

Hi everyone,
Sorry to disturb, but does anyone know if there is a way of inputting a predefined curve as a boundary in COMSOL.
For example, if I were to want to have a line of y = sin(x) as the geometry for a line, would I have to implement it as a series of points? Or could I simply implement a function?
(As of yet, I am only able to introduce a series of co-ordinates).
Cheers for the help.

Kesh

Hi
from my knowledge, COMSOL's graphical kernel uses only splines so you should then approximate your sinus surface by splines.
but there is also another method, you run first a deformation solution (with the resolution you define for the mesh) to deform your surface, and then you solve your physics. There are a few threads discussing how to deforme a flat surface to any shape known as an analytical expression, also a few presentations in the COSMOL conferences

Good luck
