After a good night, I redo my model and error vanished...

I'don't know what it comes from, but for me it's case solved.

Hi,

I'm having the same error so I will continue on this thread:

[:0:0-0:0] Error: Internal error Transformation Module PFPlusExt index Reduction Method Pantelides failed!

I'm trying to model the comand law for a UAV using Modelica and OMEDIT.

Files

To reproduce the error, load:
-DroneAxeSystem01
-drone02
-PID02
-Test05

then run Test05. the error should apear.

Plus, some additional indications are given by the consol but it's to long to copy here.
