Rotation Array

Hi folks
I'm creating a 2D geometry in version 4.0a of a structure with identiacal radial features. The 'Array' function can only make two-dimentional or one-dimensional (linear) arrays, but there is no rotation function that can copy a feature a number of times or at specified angle steps around a defined point. I can copy the feature several times and add a 'Rotate' node for each. This becomes enormously cumbersome when making many radial copies, and the number of copies and rotation angle can't be parametrized.
Does anybody know how to do this kind of rotation arrays ?. I think this is a very basic drawing function missing in COMSOL that should be included in the next version.
Any help will be greatly appreciated.

Hi
I fully agree with you, I have already sent this request as a suggestion to "support", so if we are several it might arrive quicker ;)

Hi,
You can do this in version 4.1: Add a Rotate node (right-click the Geometry node and select Transforms>Rotate). Then select the object for which you want to create copies that are rotated. You do this by entering a range of angles in the Rotation edit field using the Range function or as space- or comma-separated values. For example,
range(0,45,315)
gives seven rotated copies with an angle of 45 degrees that together with the original object are equally positioned in a full 360-degree rotation.

Hi Magnus
great thanks for a very usefull info
but what if you put some [ ] or {} around these fields accepting ranges, they are difficult to locate, and ideally (as you request for matlab functions) almost all COMSOL GUI fields SHOULD accept ranges/sets, no ?
Today there are really only a few
