Hello,

I am using IPOPT 3.11 solver in AIMMS version 4.87. 

I tried to solve a Nonlinear model using IPOPT solver, but it shows the message below in the progress windows and does nothing. Any clue on this issue or potential solution?

Thank you very much in advance.

Hi @djdmlwns. Probably the IPOPT status file provides more information. It will be printed by switching on the IPOPT option ‘Status file’. The IPOPT options can be found in the Option Tree under ‘Specific solvers’. The status file will be printed in the log folder.
