    im trying sugar out for the first time right now with matlab 6.1 (r12.1) .. im trying to repeat the examples in the manual .. but i cant get most of them to work .. is there any easy way of learning sugar 3.1 w/o trying to tear apart the demo files?

      I don't know what MUMPS is.And how to open the .net files I want use SUGAR to copulate a mirror's deformation,Below the mirror there are many electrodes which is fastened.The mirror's boundary is also fatened Can you give me some advices

        Hi,

        MUMPS is a process to fabricate MEMS devices.
        Try a web search on MUMPS.

        Please describe in more detail what kind of mirror you are trying to build. How much deformation does the mirror undergo? Are the plates of the mirror actually deforming? Depending on the geometry, your approach will differ.

        To open .net files, use your favorite text editor.

        Best,
        David

      Hi,

      You may need to set up some things to get the demos to work. Depending on which operating system you are using, set up will be different.

      If you are using windows, cd into the directory where you unzipped the files. Run sugar_init.

      If you are using a Unix based platform, make sure you add the appropriate paths to the src and lua directories. (use the addpath syntax)

      Let me know what kind of problems you have.

      Best,
      David

      The mirror I calculate is roundness with 10000um in radius.and 20um in thickness.The electrodes below the mirror is sector.It's distance to the center is about 30000um.I have 6 electrodes it's z-axes symmetric.The deformation I wanted is about
      10um.Should I do some settings in matlab to load netlist files.Can you tell me more details on how to load netlist

        Hi,

        If you have a schematic diagram, it may be easier to translate what you mean.  These scales are quite a bit larger than usual MUMPS devices (1 cm across and 20um thick), so it must be for a different process?

        Best,

      This is the problem

      >> sugar_init

      >> net=cho_load(mumps.net)
      ??? Undefined variable 'mumps'.

        Hi,

        I think you want to put quotes around your file name.

        net=cho_load('your_structure.net')

        mumps.net is an included file and gives some basic definitions. A netlist you probably want to load is one with a structure in it, like cantilever3.net in the demo directory.

      I can't find model for the roundness object within the netlist file,Can sugar do it

      hi

      im trying to define a combdrive mems and use the sugar library for that. Nevertheless i have some difficulties defining the right netlist and to understand the parameters to use with "MF_comb2d(flag, R, params, q, t, nodes, varargin)".
      Where can i find explanation about it...?
      Is there a demo available for these kind of systems?

      Thanks for your help

      Matlascu

      PS: is the function "comb.net" that appears in the user guide 3.0 existing? where?
