3 phase cable

[lkloesel@xxxxxxxxxxxxx]

Dear All,

I was trying to simulate the rotating fields around a 3 phase cable 
(see FEMM folder 3_phase_cable). In order to change the currents, I 
used modifycircprop() lua command. As you can see, in the 
pre-processor script, I changed the currents by adding 10 degrees 
to each program loop. The post-processor file will take a snap-shot
of 
the field, to which I will eventually assemble with a gif-animator to 
reveal a very nice animation of the fields.
My problem is this: FEMM hangs in the fkern portion, the biconjugate 
gradient solver just sits there. I had to add 0.5 (or 0.1) to the 
currents in order to get fkern to unhang. I believe there may be a 
bug here which warrents review. I changed the precision, but that 
didn't work. I looked for a simple lua method of rounding the
numbers 
after they were created from the sin() and cos() functions, but found 
none readily available.

Once again thanks,
Hope this helps
