hi,i had 9 set of odes,then i used dslove(numeric) and solved my equations,but now i have a question,my answers do not go more than the time 0.14 ,what can i do?i do need my answers at least for the time 5 seconds ,

i have write my code in this way :

MMM := dsolve(AA,numeric,method = rkf45, maxfun = 500000);


but when i want to evaluate MMM(1) i face this error : 

Error, (in MMM) cannot evaluate the solution further right of .14055561, maxfun limit exceeded (see ?dsolve,maxfun for details)

 can i do anything to increase the amount of maxfun ?
