Problem in AdamsBDF, getting error as not enough memory for this operation

Hi all,

I have some problem in computing ODE in AdamsBDF.

I want to use AdamsBDF function as below,

S = AdamsBDF(initial, 0, 10^6, 10^10, D)

But, when I try to use 'S' as above, I am getting an error as not enough memory for this operation.

Is there any other way to increase the sampling interval.

I attached my code below.
