Hi all,
I have a MINLP model and am using Couenne solver. The solver gives me some errors. The error message are:
" Equation 47 is general nonlinear: function vcPower results in a nonlinear expression".

From this error message I have no clue what is the reason of the problem. Can anyone help me on this issue, please?


I appreciate your help.

Best,
Mary

It sounds as if you try to solve your model as an MIQCP, not an MINLP. Log, listing, or the model itself would help to really see what's going on...
