Salut,

I find that your loop is a little weird, since r is increased by one, and your
test is r<=1, but if I increase it a little bit to see it at work, I get a
result that you might want, just by adding an initialization of omegaAlist:

Clear[et1, omegaAlist]
omegaAlist = {};
For[r = 0, r <= 10, r++,
et1 = 3.444 + r 0.001;
omegaAlist = Append[omegaAlist, N[et1]]; ]

bonne journée
