FEMM simulation showing COP 3 and 7

Can someone help me with a LUA-script for linear movement please?

You need to be way more specific than that.

OK.

I already have LUA scripts for use in FEMM to calculate torque. This script, I can edit the resolution on the steps (degrees) and edit the final sample point - say 45 degrees where the simulation stops.

I have now a need to calculate a linear movement in X and Y, not circular. A LUA script which do not calculate torque pr. degree, but force pr. distance in X or Y plane. I also want to edit resolution of the steps, and edit where the simulation stops.

What you are after requires a little vector math, if what you want indeed requires going from point A to B in a straight line. If you can share what you already have and perhaps annotate with comments what you want I can help.

Here is the FEMM simulation. Group 1 ("T T" shape) are suppose to move vertically in steps I determine by possibly editing a script. The results for each step are added up and displayed in a console.

I will then calculate an average force over a given distance to determine the required energy to raise a magnetic shield.

If you need any more info, please let me know.
