Hi experts,
I have problems with solving stuff like
\!\(pd = \[PartialD]\_t\
n[x, t] == \(-dif\)\ \[PartialD]\_\(x, x\)\ n[x, t] +
int\ Exp[\(-\[Alpha]\)\ x] - rek\ n[x, t]\)
( where dif, int, alpha and rek are constants )
I tried it via
\!\(lsg =
NDSolve[{pd, n[x, 0] == nstart,
n[0, t] == nstart, \((\[PartialD]\_x\ n[x, t] /. x ->
thickn)\) == 0},
n, {x, 0, thickn}, {t, 0, 2}]\)
( again nstart and thickn are constants )
but could not make it...
Have any advice??
Thank you,
Uli
