You can use the attach method to generate the problem without solving it.

Hello All,

To make Model->writeLp("file", "txt") work, seems I needed to call
Model->minimize(obj);
first. The same seems to be true for Model->getNumRows() and the like.
There may be a good technical reason for this, but from a user perspective it
is nice to be able to check the model in an LP  file before actually
having to solve it, especially if solving time is hours, days, weeks, ...

Maybe there is a better solution?

thanks and best regards,
