Importing data file to mesh in pdetool?

Greetings all,

    I have been familiarizing myself with pdeTool for Finite Element applications. I was wondering, can you import data from a data file into the pdetool GUI and mesh it that way? My data actually corresponds to a certain geological feature, so it does have shape, but not the rectangle or circle in pdetool, i.e., it's not uniform geometry, and it would be easier to read it in.

    Please let me know your thoughts - I'd like to try it.

    Thanks!

Hi Jesse,

I don't know of any way to import geometry into the pdetool GUI.

However, an alternative is to use the PDE Toolbox command-line API. If you can represent your geometry as a collection of n-sided polygons, you can pass this to function decsg. decsg returns a representation of the geometry that can be plotted using the pdegplot function and meshed using the initmesh function.

Bill,

Sorry for the delay in getting back to you - my semester just started up, so you probably know how that goes!

About pdetool, well, is there to simulate other shapes other than rectangles and circles? How about something like a saw-tooth?

Thanks!
