Given an OPL model written using the OPL IDE, how can you convert the model to a format such that it can be solved using the cplex interactive optimizer?

In ILOG-Script use

cplex.exportModel("myProblem.lp");

to dump as an LP-file (use different file extension to dump other supported formats).

Alternatively you can set it in the ops-file.

Hi,

a way to do that is to add an ops file in your run configuration and then select mps or lp as the export format

I tried using the ops. file option to save my .mod file in mps/lp format. After choosing this export format option the OPL model shows an error and stops.

Hi,

what error message do you get?

Hi
Actually this was a problem with the OPL 6.3 version. I tried newer version and its working fine. The error message was blank. The IDE would show one blank error and stop the execution.

One more remark:
You should note that you will not necessarily get the same run behaviour when you solve the problem with CPLEX standalone solver or within OPL, as some solver settings might be different and variables/constraints might have a different sorting order.
