Subject: Re: [TSSP] Toroid field stress
Hi All, BOY!! This has been a rough few days for finding E-Tesla6 bugs... Thursday - They found the rail crash problem. Friday - The primary higher than the secondary base problem. Saturday - Stress grid does not scale to different measurement units Its that darn metric system... :-)) Apparently, the stress array is scaled wrong by a factor of 2.54 when using cm... I tried it with mm and everything worked fine but the max stress is ~100 volts now... :-p The stress output array was only used for plotting pretty pictures before... :-)) Of course, "I" always used inches. I knew the voltage calculation array was right for other measurement systems but thinking about the stress array had me worried... Thus, the 600 array I did and got an answer of 10.2 kV should have been 10.2 x 2.54 = 25.9kV. Mysteriously close to the 26kV we all though it should be :-)) So It looks like E-Tesla6 may indeed be able to do this stress stuff for our purposes with yet another minor revision.....
