Creating Geometry with an algorithm

I am wondering if there is a way of creating tedious geometries that happen to lend themselves to being defined by a simple algorithm easily, without requiring the MATLAB interface.

For example, I want to create many successive line segments in a 2D simulation whose lengths and in-between gaps are predefined with an algorithm that calculates them. I can envision doing the calculation outside of COMSOL, then importing these as a parameter list and then using it as a lookup table for a COMSOL algorithm that creates these lines. Any pointers for accomplishing this easily would be appreciated.

Thanks,
Ozgur

Have you considered using an app? They allow programming through methods written in JAVA. This can be used to automate repetitive tasks in pre- or post-processing.

I have added an example that shows how to create a repetitive geometry in the Application Builder in this thread:

There is now also a recorded webinar that shows how to generate a geometry algorithmically with the Application Builder:

Edit: There is a new blog illustrating the use of the App Builder to build a randomized geometry: www.comsol.com/blogs/how-to-create-a-randomized-geometry-using-model-methods/

Hi Jeff and if we have never used JAVA ,, the app builder could be always used or not?

I am assuming your question is still with regards to automating geometry creation. Doing so in the Application Builder does require some Java coding.

There are many other things you can do in the Application Builder that do not require any Java coding.

You can also automate creation without using the Application Builder by using MATLAB coding instead (This requires LiveLink for MATLAB).

The application builder sounds like a great way to achieve this; another easy solution may be using livelink with excel.
