I'm trying to maximize function like this:
Maximize[{(n\[Pi]D^2 \[Epsilon])/(
4 (r + (4 (L + \[Pi]nD) \[Rho])/(p^2 \[Pi]))), n > 0, D > 0, p > 0,
n*p < 0.05}, {n, D, p}]
However, the only result is: NMaximize::nnum: The function value -(...) is not a number at {D,n,p} = {0.657799,1.42836,0.00858598}.
I totally don't get it because the function has a finite value for this. I'd be grateful for any help. I tried to use both Maximize and NMaximize.
