Hi,

I am perplexed by the behavior of AbsoluteOptions on NDSolve. I tried
getting the actual value of StartingStepSize and got something weird.

In[]:= AbsoluteOptions[NDSolve[eqSys, {c[x, t], T[x, t]}, {x, 0, xb},
{t, 0,1}]],StartingStepSize]
Out[]:= {{AbsoluteOptions[c[x,t]->InterpolatingFunction[{{0.,5.*10^-6},
{0.,1.}},<>][x,t],StartingStepSize],AbsoluteOptions[T[x,t]-
>InterpolatingFunction[{{0.,5.*10^-6},{0.,1.}},<>]
[x,t],StartingStepSize]}}

Isn't there a way to fetch absolute options from NDSolve?

Thanks in advance
