Description
The constructed initial system is wrong in certain cases:
msl32/Modelica.Fluid.Examples.AST_BatchPlant.BatchPlant_StandardWater.mos msl32/Modelica.Fluid.Examples.PumpingSystem.mos
Both examples produces the following output:
Notification: The given system is mixed-determined. [index > 0] Notification: The given system is mixed-determined. [index > 1] Notification: The given system is mixed-determined. [index > 2] Notification: The given system is mixed-determined. [index > 3] Warning: No system for the symbolic initialization was generated. A method using numerical algorithms will be used instead.
This means that the initial system is structural singular. I assume that there are a few implicit defined conditions missing.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

Removing the pre1.9.4 milestone in favor of 1.9.4.
Note:
See TracTickets
for help on using tickets.
Both models get now initialized (r24296).
