Hi,
I've run into the same thing, kind of. Recently,
I've been using FEMM to make animations. For each frame (in this example),
I have to adjust the angular offset of magnetization to simulate rotating
magnets and moving fields. To get a smooth animation, I have to use at least 16
frames; with nonlinear materials the crunch time is about a day, and it must be
tended to manually. (16 frames is still pretty chunky; 36 or 72 frames would be
awesome but I do not have the time or patience to mess around
with it)
Isn't it possible to invent a "shell" for FEMM,
which will iteratively run fkern, each time after changing some variable(s)
in the model? Then, the changing parameters could be selected from a list of all
properties (frequency, materials, magnetization direction, point
coordinates, you name it) and the progression of values given either by a
list (100, 200, 300...) or a parsed formula (i.e., x = x + 100). This is one
suggestion out of many ways it can be done.
I feel this would save a lot of time, for problems
that depend on multiple solutions. A colleague of mine did a moving simulation
in FEMM using something like 180 frames - and he did that all by hand.This
is a lot of babysitting, when you have to solve each frame
individually (or in batches of a few, with a couple windows open, each running
FKERN... but this "divided attention" multitasking is SLOWER,
overall, and crashes too often.)
If I knew C++ I might try making an
iterative shell of my own... it seems like it would not be so hard to do. I
don't know C, though, and have no spare time to learn it now. (I barely have the
spare time to manually iterate the simulations!)
Regards,
Graham
