[Coin-ipopt] FATAL ERROR : Get_Ratio_a_2

[Carl Damon Laird]

The message,

>     FATAL ERROR : Get_Ratio_a_2
>               Product of Grid Spacing <  0.2225074-300

is not one coming from IPOPT. Likely this message is coming from the code 
that sets up your optimal control problem.

Cheers,

Carl.
