Hi, I am using femm to model a
solenoid. I need to plot a force/stroke
curve, and so will have to manually move the plunger in femm and process each
position separately. Here isan
idea I have for reducing the amount of work I have to do. This may be a useful technique for
batch processing. I plan to define
the model in femm, and then split and save it in two (could be more for more
complex designs) parts, with the moving elements in a separate file to the
static elements. (Delete the
moving parts, save the static ones, reload, delete static parts…) I plan to write a simple program (basic
transforms like move, rotate) to manipulate the moving elements and merge them
with the static ones into a single file for processing. It should be fairly easy to create a
group of files, one for each position I wish to model. It doesn’t solve all the problems, but
may be useful to some. If you
were to change the file formats to one that included a description of each file
element (e.g. xml) it would make it easier to process the data outside of FEMM. e.g. current density could be
manipulated, elements could be
move. XML would be handy as it is
human readable(ish), supports data structures while describing them at the same
time, and there is programming support for it in Visual Basic and Visual C++
via msxml.dll. To process
the file would be simple if femm could be triggered through the command line. As far as I can tell all the required
information is in the .FEM file. Generating
integrals would still require something more involved, and DDE sounds like a
good solution. I will post my
pre-processor once it is working. Adrian -----Original
