  • Owner changed from wbraun to lochel
  • Status changed from new to assigned
  • Summary changed from DAES generated by the NF do not allow symbolic jacobian generation to DAES generated by the NF do not pass the initialization phase

It's not symbolic Jacobian, it's something in the creation of the initialization problem.

The model now seems to be overdetermined instead. I'm not sure if that's an improvement or not.

  • Resolution set to fixed
  • Status changed from assigned to closed

Me neither. I would wait to worry about overdetermined systems until you have managed this problem that was already reported elsewhere.
