about defining Y in reference frame

Please login with a confirmed email address before reporting spam

Hi


From the equation ,(in the cavity) V(t0) = -0.01+0.02*Y/5e-2[m]

Is Y the reference coordinate?

Can I define Y if i'd like to limit solving Y at 5e-6[m] instead of time range?



Thank you very much for your help

Hi

if you are in 2D or 3D norally y an Y are the 2nd space coordinate (one for the reference frame one for the spatial frame (or the opposite I never get it right pls check carefully, it has its importance. Note also that between 3.5 and 4 there are chnges in the default behaviour (and names) of the frames.

finally in 3.5 take some care with units and fractions, if I remember right 1/x[m] is NOT the same as 1/(x[m]) but pls cross check

Good luck
